1- HVAC DESIGN FOR A UNIVERSITY BUILDING USING GEOTHERMAL HORIZONTAL AND VERTICAL LOOP HEAT SINK FOR CONDENSER HEAT REJECTION

Summer days in Egypt are extremely hot and dry, Reaching the comfort zone is essential especially in this atmosphere, this will not happen without applying a proper air conditioning system that could be adapted with such weather conditions. Many traditional air conditioning systems are already in use, but with very high operating costs due to large consumption of electricity. Nowadays, Egypt witnesses an energy crisis concerning production of electricity from traditional fossil fuels. Thus, it is essential to find alternative energy solutions in cooling which can be sustainable.
As part of the British University in Egypt initiative to increase campus sustainability, geothermal systems have been identified as an attractive option which can solve the energy crisis in summer times that arises in Egypt. Geothermal cooling systems take advantage of the stable temperature underground using a piping system, commonly referred to as a “loop.” Water circulates in the loop to exchange heat between the building and the earth. The purpose of this report is to analyze the economic feasibility of installing such a system on the BUE Campus. In this paper we are going to investigate the admission building at the university, to check whether it is better to implement traditional central air cooling system or geothermal cooling system. The comparison would be based upon the initial cost in addition to the operating cost for both systems.
Geothermal systems are composed of three main components: The heat pump, the earth connection/ground loop, and the building distribution system. The type of heat pump that must be used for this system is a liquid-to-liquid heat pump as the admission building use water for space cooling via air handlers. In terms of the ground loop configuration, it was decided that closed loop horizontal pipes are best suited to admission building due to the fact that cost of digging for horizontal loop is less and there is enough area of garden in front of the building which can be exploited to set up the loops below it. The paper mainly focuses on performing a case study on the admission building at the University. This would be through calculating the total cooling load of the building which is estimated via the HAP software package (hourly analysis program). This would lead to selection of the pump required for the ground loop design. Furthermore, an analysis for the soil should be held to check for the heat transfer rates and selection of the material for the pipelines. During this phase, we would use (Ground Loop Design) which is the leading software suite for geothermal heat pump and ground heat exchanger system design. Giving data about; Thermal Conductivity Module, Piping Module, Hourly Model Simulations, Time of Use Modelling, Predicted KWH Consumption, Weighted Average Thermal Conductivity Calculator. After all, the cost for constructing such a system can be estimated as long as with operating cost to be compared with traditional system.

2-Defects Evolution in high efficiency third generation photovoltaic cells

The research will report and show analysis and study on applying the embedded void approach (EVA) that was technologically advanced by Dr. Salah Bedair to reduce the thermal stresses in GaN/Si film. The Gallium Nitride (GaN) and Silicon (Si) both carries big semiconducting properties that helps them to be influential and powerful materials in the photovoltaics (PV) field, but the superior properties that the GaN and Si have is not enough to stop and prevent any thermal and mismatch stresses because the GaN and Si have different coefficient of thermal expansion and constant lattice mismatch that are the main limitations that leads to that. The thermal and mismatch stresses that happens will create misfit dislocations and defects at the interface between the GaN and Si that will decrease the solar cells efficiency. A progress has happened to increase the solar cells efficiency again, and this can be done through a reduction in the dislocation density at the interface between GaN and Si and this will be the main part to be examined in this paper.
A detailed study will be shown here on the GaN over Si model to record the consequence of EVA on the thin film and interface stresses using Abaqus and a constitutive model to calculate the dislocation density using Damask. The upcoming work that will be introduced in this paper will carry complicated meshes that have voids inside it, and a well-studied periodic boundary conditions (PBC) this is applied for both external and internal surfaces. This work will be done to simulate the contact around the voids and the dislocation movement in process from initial to dynamic state. This paper will report the effect of EVA on dislocation density.

3-ENERGY SAVING USING ASHRAE 90.1-2013 FOR HOSPITAL CASE STUDY IN EGYPT

As commercial buildings became one of the biggest sectors in consuming power, the reduction in its consumption became Inevitable. This study aims to save power consumption in commercial health care buildings by optimizing an existing Chilled Water System for a hospital in Egypt and simulate the results.
In this paper, HVAC (Heating, Ventilation and Air-conditioning) power consumption is studied as it consumes a large portion of Egyptian commercial buildings energy consumption.
Site visits and studies are carried out for optimizing the system that will be proposed to reduce HVAC System power consumption using the application and guidelines of ASHRAE 90.1 .2013 for energy saving.
All Building envelope parameters will be studied through different scenarios and their effect on the total load and the power consumption. Energy saving will affect primarily the size of chillers, pumps, compressors, AHU’s and fan coils as they are the main components that consume large amounts of power.
This comparison on the case study of an existing system and proposed system will be utilized with the aid of HAP (hourly analysis program) software to make an actual simulation before and after the optimization, where the simulation will also include the cost analysis and the annual power consumption for maximum efficiency.
Following the guide lines of ASHRAE 90.1 for this case study will lead to power consumption saving by more than 50% that will help in solving the overload power consumption during the peak hours in Cairo- Egypt. This paper would be a guideline for all hospitals with chilled water systems all across Egypt.

4-DESIGN, MANFACTURING AND FIELD TESTING OF A ONE KILO WATT LENS TYPE WIND TURBINE

The present work clarifies the design of 1-kilowatt wind lens turbine. A lens design was implemented so that the dilemma of low wind energy production could be solved at low wind areas. The idea of wind lens is to accelerate the wind motion through rotor by making vortices at the exit of the lens. The formation of vortices is due to the brim attached to the lens exit which generate a region of low pressure that tend to increase the mass flow rate of air through the rotor, and thus more power output is achieved. A statistical study of experiments was implemented by changing characteristic dimensions of lens as throat, inlet, outlet, brim diameters and the length. The purpose of this statistical study is to enhance the flow of air through the lens, so that maximum possible power is obtained. The design of wind lens was justified using computational fluid dynamics (CFD) so that a vital experiment of wind lens could be investigated using simulations. An appropriate design of rotor was designed using Q-blade so that that the optimum performance of wind lens turbine could be achieved by choosing an appropriate NACA airfoil. A column design was implemented so that various load on the structure of wind lens turbine could be sustained by the column. All components of wind lens turbine as wind lens, base, column, hub and nacelle were manufactured except the electric generator.

5-Design and Development of an Unattended Driverless Rail Network

The aim of this project is to utilise the concept of full automatic control over railway networks also known as unattended train operation (UTO) in city mass transit systems. This is done through development of a prototype model using toy trains as the main subjects to be controlled. This model will demonstrate the control architecture and assess the feasibility of the developed concept. The control over the network and the trains is to be done through a remote Arduino Mega 2560 where the central processing occurs. Wireless communication between the central controller and the individual trains is achieved through a transmitting Radio Frequency module nRF24L01 which is the nervous system transmitting control signals. Each train is equipped with a receiver RF module and an Arduino Nano. Obstacle detection and collision avoidance are achieved by two simultaneous techniques. The first is a proximity sensor fitted on the train while the second is proximity sensors distributed along the tracks especially at a turnout intersection (Y-shaped intersection).
The report presents and discusses real life control methods in unattended train operations with layout examples. Additionally, the progress made so far in designing the model railway network and the various methods of control are described together with the selected hardware and electronic components. Subsequently, the problems faced and their solutions, electronic components counterpart’s comparison and justification and Arduino coding progress are described.

6-Alternative layers in hierarchical nanolattices metamaterials for optimized strength

Hierarchical Ceramic-nanolattice is an architected metamaterial that composes of hollow- ceramic tubes, this hierarchy structure provided these tubes with ductile and recoverability properties for a limited strength. This paper suggests a new composition for these tubes which allows higher strength and stiffness by manipulating their structure by adding concentric layers of alumina (ceramic) and Polymethyl methacrylate (PMMA) inspired from the biological structure of Euplectella sea-glass sponge which has rigid and flexible structure to implicit their living conditions in the deep oceans.

7-Investigation of the effect of using Nano-material as fuel additive

Since the spark of the industrial revolution, The Automotive industry have increasingly became one of the most recognizable industries worldwide that have a gross and massive scientific research units and labs to keep pace with the increasing demand of transportation means not only that but also as the industry became a player in the growth of the nations’ economies.
As a consequence of this huge rate of automotive industry mass production the rates of fuel burning whether gasoline or diesel also increased and this result in an increase of Greenhouse and C𝑂2 gases emissions which will affect the environment and surrounding ecosystem negatively. Due to the previous statement importance, many researches and scientific studies have been processed to try to find a solution of enhancing the consumption rates of fuel that will lead to better vehicles engine performance, less fuel being used and relatively less harmful exhaust emission. According to (Haraguchi,2011) [1], It is estimated that the number of used cars by 2020 will be around 1.2 billion and might reach 1.6 billion cars in 2030 [1], this will lead to terrible problems concerning the increase of pollution and global temperature due to the more use of fuel being burned and its emissions. A way to improve the engines performance and reduce rate of fuel consumption is using the Nano technology in enhancing the type of fuels being used.
Nano technology is basically the engineering or construction of a unit or system at the molecular level or scale. Many studies and researches have widely introduced Nano particle materials that have the ability to enhance the fuel characteristics and in return enhance the rate of fuel consumption and reduce pollution emission to the environment such as metal oxide Nano additives, magnetic Nano fluid, Nano organic additive, carbon nanotube, mixed Nano additives and others. Scientists have found that many materials have unique and terrific change of properties and characteristics in the Nano size scale and that is why many researches have extensively been made to use this technology in a way to enhance the automobiles fuel being used and thus enhancement of all factors relying on fuel burning. However, the major problem concerning the use of Nano materials is their expensive cost and high cost of engineering processing processes.

8-ENHANCING FACILITY PRODUCTIVITY AND ELEVATING CAPACITY IN THE EGYPTIAN INDUSTRIAL MARKET

Time and labour has always been the most treasured commodity in the world, while the modern industry utilizes this enormous labour power and time in order to manufacture goods responsible for enhancing the life of the human race. Therefore, it is a must to utilize the labour's working hours beneficially to minimize wastes in order to maximise production capacity. Waste minimization is achieved recently by lean manufacturing techniques which are inspired by the first Toyota Production system established by Taichi Ohno. This dissertation focuses on enhancing facility productivity and elevating capacity in the Egyptian industrial market. ABB assembly line has been chosen to implement with the intention of elevating the capacity. The data will be analysed using different software such as Arena and Visio for identifying the production process wastes. Since industrial organizations became so competitive in order to anticipate the market needs and sustain their market share, waste minimization became inevitable. Light has been shed on the waste causes; moreover, new layout has been proposed in order to increase the capacity by 14%.
