Implementation And Analysis Of A 1.4l Turbo Liquid Cooled Cac And Ac Condenser System, Mitchell Zajac
Implementation And Analysis Of A 1.4l Turbo Liquid Cooled Cac And Ac Condenser System, Mitchell Zajac
Masters Theses
This project report serves as a continuation and finalization of an overall experience with the design process including working on the development of system components, working with automotive industry leaders, suppliers and dealing with the aspects of business and production feasibility. The development of a dual level cooling concept to apply Centro Richerche Fiat established components on a Chrysler Group vehicle application was the foundation of the design project completed in December 2012 by Matt Cutler and Mitch Zajac. The development of this system aimed to decrease overall vehicle power consumption, minimize overall system packaging space, and to increase vehicle …
Analytical Solutions For A Large-Scale Long-Lived Rotating Layer Of Fluid Heated Underneath, Pouya Jalilian
Analytical Solutions For A Large-Scale Long-Lived Rotating Layer Of Fluid Heated Underneath, Pouya Jalilian
Masters Theses
In this work, the system of equations for a large- scale long lived rotating layer of fluid with the deformable upper free surface and non-deformable lower free surface heated underneath has been reviewed and derived. The quasi-geostrophic approximation, the beta effect and the method of multi-scale expansions have been employed to and as a result, an equation governing the evolution of large-scale perturbations, has been derived. The effect of each term present in the upper surface deformation equation has been analyzed and the analytical solutions have been obtained by virtue of employing auxiliary Riccati equation method. The soliton solutions obtained …
Organic Solar Cells Based On High Dielectric Constant Materials: An Approach To Increase Efficiency, Khalil Jumah Tawfiq Hamam
Organic Solar Cells Based On High Dielectric Constant Materials: An Approach To Increase Efficiency, Khalil Jumah Tawfiq Hamam
Dissertations
The efficiency of organic solar cells still lags behind inorganic solar cells due to their low dielectric constant which results in a weakly screened columbic attraction between the photogenerated electron-hole system, therefore the probability of charge separating is low. Having an organic material with a high dielectric constant could be the solution to get separated charges or at least weakly bounded electron-hole pairs. Therefore, high dielectric constant materials have been investigated and studied by measuring modified metal-phthalocyanine (MePc) and polyaniline in pellets and thin films. The dielectric constant was investigated as a function of temperature and frequency in the range …
Noise And Vibration Reduction Of A Clothes Dryer, Daniel O'Hare
Noise And Vibration Reduction Of A Clothes Dryer, Daniel O'Hare
Honors Theses
As placement of washers and dryers becomes common in apartment buildings and high rises, noise generated by the dryer becomes a nuisance to the inhabitants. Whirlpool Corporation is experiencing this issue first hand with their Horizon model long vent dryers. A focus was placed on noise and vibrations caused by the dryer motor, because its vibrations are transferred throughout the structure of the dryer. The motor causing sound problems was a modified motor from the standard model, including a speed-increasing attachment in order to operate the fan at an increased speed. Through sound and vibration measurements, structural and airborne noise …
Broncoblade: An Open Source Wind Turbine Blade Analysis Tool, Alex R. Quinlan
Broncoblade: An Open Source Wind Turbine Blade Analysis Tool, Alex R. Quinlan
Masters Theses
This thesis reports the development and validation of BroncoBlade, a horizontal axis wind turbine analysis tool. BroncoBlade prepares finite element models and integrates them with an aeroelastic simulator. Analysis results for the SNL100-00 baseline blade are evaluated against reference results published by Sandia National Laboratories. Variations on the SNL100-00 blade incorporating carbon fiber are compared to the baseline blade.
Development Of Cfd Models For The Purposes Of Exploring Free Surface Wave Phenomena, Leonard P. Stoehr
Development Of Cfd Models For The Purposes Of Exploring Free Surface Wave Phenomena, Leonard P. Stoehr
Masters Theses
With the push for finding alternative, green energy sources, the harnessing of energy from ocean and lake waves is becoming a more researched field. To fully understand the behavior of wave interactions and optimize designs to extract this energy, it is necessary to develop computer models that can accurately replicate this behavior. A case is presented in which previous work done using the wave tank found in the Western Michigan University fluids lab is examined. The case involves harnessing the energy generated by ocean waves through the usage of plates of different shapes resting horizontally on the water’s surface. The …
