High Dimensional Non-Linear Optimization Of Molecular Models, Joseph C. Fogarty
High Dimensional Non-Linear Optimization Of Molecular Models, Joseph C. Fogarty
USF Tampa Graduate Theses and Dissertations
Molecular models allow computer simulations to predict the microscopic properties of macroscopic systems. Molecular modeling can also provide a fully understood test system for the application of theoretical methods. The power of a model lies in the accuracy of the parameter values which govern its mathematical behavior. In this work, a new software, called ParOpt, for general high dimensional non-linear optimization will be presented. The software provides a very general framework for the optimization of a wide variety of parameter sets. The software is especially powerful when applied to the difficult task of molecular model parameter optimization. Three applications of …
Organic Fluids And Passive Cooling In A Supercritical Rankine Cycle For Power Generation From Low Grade Heat Sources, Rachana Vidhi
Organic Fluids And Passive Cooling In A Supercritical Rankine Cycle For Power Generation From Low Grade Heat Sources, Rachana Vidhi
USF Tampa Graduate Theses and Dissertations
Low grade heat sources have a large amount of thermal energy content. Due to low temperature, the conventional power generation technologies result in lower efficiency and hence cannot be used. In order to efficiently generate power, alternate methods need to be used. In this study, a supercritical organic Rankine cycle was used for heat source temperatures varying from 125°C to 200°C. Organic refrigerants with zero ozone depletion potential and their mixtures were selected as working fluid for this study while the cooling water temperature was changed from 10-25°C. Operating pressure of the cycle has been optimized for each fluid at …
