This product is a zip file that contains files that consist of PowerPoint slides synchronized with the audio-recording of the speaker, PDF files of the slides, and audio only (mp3 format) as noted.This seminar will explore the numerical and computational challenges, and the accompanying solutions, associated with modeling vapor compression systems and their components with an emphasis on compressor modeling. Speakers will explain the challenges resulting from the stiffness of the non-linear Ordinary Differential Equations (ODE’s) that govern the behavior ofpositive-displacement compressors. Additionally, an assessment of the most efficient compressor modeling platform will be presented. Finally, a study of the challenges associated with modeling the system dynamics of a complete vapor compression cycle will be presented.Discussion of the Numerical Methods Used in Positive Displacement Comprehensive Mechanistic Models: Case Study Using the Z-CompressorCraig Bradshaw, Ph.D., Member1, Davide Ziviani, Ph.D., Member2 and Eckhard Groll, Dr.Ing., Fellow ASHRAE2, (1)Oklahoma State University, Stillwater, OK, (2)Purdue University, West Lafayette, INQuantitative and Qualitative Evaluation of Various Positive-Displacement Compressor Modeling PlatformsMohsin Tanveer, Student Member and Craig Bradshaw, Ph.D., Member, Oklahoma State University, Stillwater, OKChallenges of Charge-Sensitive Dynamic Modeling and Control Scheme Implementations for Heat Pump ApplicationsTyler Shelly, Student Member, Davide Ziviani, Ph.D., Member, Justin Weibel, Ph.D. and Eckhard Groll, Dr.Ing., Fellow ASHRAE, Purdue University, West Lafayette, IN
