Optimization Of Analytical Inverse Heat Transfer Recovery Solution, Nathan Schick
This thesis describes the different methods used when trying to solve inverse heat transfer problems, particularly those involving recovering heat flux. There are currently several techniques to measure the temperature history in an object subjected to heat transfer using various temperature sensors, however these types of sensors are gradually being replaced by Temperature Sensitive Paints (TSP), a technique that is more accurate and provides a better spatial resolution. TSP is a polymer that is applied on a base object. Changes in temperature in the polymer result in variations of the luminescence intensity in the paint. These variations can be captured ...
Liquid-To-Liquid Low Grade Waste Heat Recovery Using A Two-Channel Loop, Waleed Farwana
The use of thermoelectric generators (TEGs) for producing electric energy from low grade “waste heat” has been theorized to provide a sustainable and low-cost energy source for electric power plants. The purpose of this study is to model and experimentally validate a TEG device that takes advantage of low grade waste heat (approximately 100-150 degrees Celsius) in liquid form in order to generate power that can be used for various applications in the surrounding environment. This research aims to demonstrate that optimized TEG designs bear the potential to compete with other methods of low grade waste heat energy harvesting in ...
Simulation Of An Intake Manifold Pre-Heater For Cold Diesel Engine Startup, Patrick K. Kreun
Ensuring consistent, reliable diesel engine startups in cold temperatures is of utmost importance in a number of applications. Under extreme temperatures, the use of glow plugs is complemented by intake manifold heaters. In these, the energy released from combustion increases the intake air temperature before the air enters the main combustion chamber. Since the process also alters the stoichiometry of the fuel-air mixture at the intake ports, the preheater operation must be optimized in order to guarantee successful and reliable in-cylinder combustion during engine startups. This paper describes the development of an intake manifold model incorporating an air pre-heater for ...
Analytical Performance Evaluation Of Thermoelectric Modules Using Effective Material Properties, Sean Lwe Leslie Weera
Designers often face the predicament of non-standardized forms of performance data provided by thermoelectric module manufacturers. Other than experimental means the only method to evaluate the performance of a product would be through analytical modeling using material properties that are usually undisclosed and unknown. This work studies the theoretical approach of obtaining such material properties using the maximum operating parameters reported by the manufacturers. These values are then analytically employed to evaluate the performances of these thermoelectric modules. Experimental means are also devised and carried out on these test samples to validate the integrity of the results. Three-way comparisons between ...
