Abstract:

This thesis attempts to improve, prepare for release, and verify the accuracy of the expert system code entitled Design Simulation for Thermoacoustic Research DSTAR created previously by LT. Eric Purdy. DSTAR allows a unique new approach for the rapid design and simulation of thermoacoustic devices utilizing a Microsoft Windows TM compliant interface to construct any given thermoacoustic model at runtime. The approach to simulation involves the solution of a one-dimensional acoustic wave equation simultaneously with an energy flow equation from one end of the specified device to the other, including additional lumped elements. The resulting solution is available as both a graphical and text-based output. In order to prepare for release, significant additions to the engine code and interface were completed. Additionally, theoretical results obtained by the DSTAR system code were compared to actual measured values in order to demonstrate potential engineering design applicability.
