Gasification Based Waste Tire Integrated Energy Conversion Systems, Karah Powell
Gasification Based Waste Tire Integrated Energy Conversion Systems, Karah Powell
Honors Theses
The objective of this study was to evaluate the operating parameters impacts on the performance of a gasification-based waste tire integrated energy conversion system. In this system, the waste tires are put into a downdraft gasifier that is providing fuel for a solid oxide fuel cell (SOFC). The system is evaluated by the syngas production, power generation, and overall efficiency under various operating conditions. A hybrid 1-D model was adopted to perform a parametric study of the tire gasification and calculations were done to estimate the integrated system power generation and overall efficiency using MATLAB. Three parameters were studied: the …
Feasibility Study Of Portable Solar Powered Blood Storing Refrigerator, Saroj Subedi
Feasibility Study Of Portable Solar Powered Blood Storing Refrigerator, Saroj Subedi
Honors Theses
This report is focused on the preliminary feasibility of portable solar-powered blood-storing refrigerators primarily based on calculations of energy required to maintain the temperature of the refrigerator, the electricity required throughout the day, calculating sufficiency of power supplied by the solar panel, and selection of battery for power storage. The method and the trend of a feasibility study involve the study of blood properties, separation of blood components after donation, and their storage conditions. Then, the portable size of the refrigeration has been proposed with three different compartments for storage of each blood component. The further methods involve the selection …
Evaluation And Sizing Of Solar Powered Reverse Osmosis Water Desalination System, Sandip Subedi
Evaluation And Sizing Of Solar Powered Reverse Osmosis Water Desalination System, Sandip Subedi
Honors Theses
About 71 % of the surface of Earth is water, out of which around 2.5 % is freshwater. The majority of the surface of Earth is occupied by seawater which also contains dissolved salt. The salt concentration in seawater makes it toxic to humans because the human body is unable to get rid of the salt that comes from seawater. The demand for fresh water is increasing due to the rise in global population. In this context, desalinated seawater is considered as a viable resource to meet the growing demand for fresh water. Desalination process is highly energy intensive due …
Parametric Design Of Flywheel For An Electric Punch Press, Prashant Dhakal
Parametric Design Of Flywheel For An Electric Punch Press, Prashant Dhakal
Honors Theses
Almost all designs start with a design requirement. These may be weight, volume, clearance, and even custom calculations. Finding a solution that meets these requirements often involves tedious and time-consuming iterations. Once the solution has been found, the design must be optimized to find the best possible solution. Finding the ‘best possible design’ requires substantial time and effort dedicated to iterating and analyzing the potential model solutions. This is where Parametric design comes into play. The Parametric design aids in specifying the key parameters of the design and makes changes interactively, with the model updating automatically. The purpose of this …
Computational Study On Suppression Of Airfoil Flow Separation Using High-Frequency Translational Surface Actuation, Bibek Gupta
Computational Study On Suppression Of Airfoil Flow Separation Using High-Frequency Translational Surface Actuation, Bibek Gupta
Honors Theses
Flow separation is a phenomenon that occurs when pressure increases in the streamwise direction of a flow, making a distinctive boundary layer or separation bubble. It causes aircraft to experience an increase in drag and noise and a decrease in a lift, hence degrading their aviation performance. This study uses numerical simulations to understand better the effects of high-frequency translational surface actuation (HFTSA) on flow separation control. The numerical simulations mimic the experimental parameters of an experiment performed by Okoye et al. on using the HFTSA system to control flow separation. A symmetrical airfoil structure of chord length of 0.3 …
Sizing And Economics Of Solar Powered Indoor Swimming Pool, Aman Bhatta
Sizing And Economics Of Solar Powered Indoor Swimming Pool, Aman Bhatta
Honors Theses
With increasing global population and aspiration for higher standards for living, there is a rapid increase in demand for energy. With the concerns of climate change becoming ever more pressing, a shift from the conventional energy source to an alternative green version to meet the energy demand could be of significant interest. A large amount of energy is required to maintain water temperature in the swimming pool at a human comfort temperature. Several studies have been performed to calculate and evaluate the feasibility of powering thermal systems for swimming pools using solar energy. Still, extensive analysis using solar thermal energy …
