A Computational Study Of A Photovoltaic Compound Parabolic Concentrator, William M. Vance Jan 2015

A Computational Study Of A Photovoltaic Compound Parabolic Concentrator, William M. Vance

Browse all Theses and Dissertations

Routines have been written and added to the Wright State developed solar system simulation program called Solar_PVHFC to model incident solar radiation for a compound parabolic concentrator (CPC) that uses solar panels (photovoltaic panels) to produce electrical energy. Solar_PVHFC is a program that models a solar energy system composed of solar panels to produce electricity from the sun, hydrogen storage tanks to chemically store the energy produced by the solar panels, and fuel cells to convert between electrical and chemical energy when required. Solar_PVHFC features several adjustable parameters to model a solar panel, hydrogen storage, and fuel cell system. Now …


Verification And Validation Of A Transient Heat Exchanger Model, Jayme Lee Carper Jan 2015

Verification And Validation Of A Transient Heat Exchanger Model, Jayme Lee Carper

Browse all Theses and Dissertations

A statistical based verification and validation process is applied to the transient modeling of a shell and tube heat exchanger. A generic model of a heat exchanger was developed based on first principles as a sub-system of a larger thermal system model. This model was originally created without any experimental data, as it was not readily available. To provide the data necessary to apply the validation process, a thermal emulator was designed and built that allowed control of all system inputs to the heat exchanger, while also providing the instrumentation to record all required data. A wide test matrix was …
