Modeling Pulse Tube Coolers with the MS*2 Stirling Cycle Code

Towards Fully Three-Dimensional Virtual Stirling Convertors For Multi-Physics Analysis and Optimization

“…At the level of multidimensional analysis, relatively little has been completed because the third order analysis tools, including Sage, (Gedeon, 1994) and to some extent, DeltaE (Ward and Swift, 2001) and MS*2 Stirling Cycle Code (Mitchell, 1998), are faster and for the most part have been adequate engineering design tools. However, to improve efficiency, reliability, and supplement experimental testing (to understand and reduce losses, identify component temperatures, and assist in sensor calibration, correlation, and placement) it will require a higher fidelity look at the actual flow features and heat transfer throughout the engine.…”

“…Significant efforts have been made in the last decade in expanding the designer's analysis options for building improved free-piston Stirling engines (Beale, 1969) ranging from thermal, structural and magnetic dynamic analysis (time-stepped magnetostatic analysis) (Geng, 2000), computer-assisteddesign (CAD) software for complete threedimensional part design (Chua, 2003), onedimensional thermodynamic cycle analysis (ARCOPTR, 2003;Bauwens, 1996;Ward and Swift, 2001;Gedeon, 1989;Gedeon, 1994;Lu and Cheng, 2003;Mitchell, 1998;Kuriyama et al, 1998;Schock, 1978;Swift and Ward, 1996) and optimization, and one-dimensional system mechano-dynamic simulations (Benvenuto and Monte, 1995; Lewandowski and Regan, 2004;Regan, 2003;Ulusoy, 1994). A review of the progress in Stirling analysis shows a steady relaxation of assumptions/limitations imposed on the analysis over the past century .…”
