Numerical and experimental study of thermoacoustic pulse tube refrigerator

A comparative analysis of various numerical methods of the pulse tube cooler was provided. The thermodynamic model for estimation of the minimum temperature level ofcold heat exchanger at a predetermined ratio of the pulse tube and the compliance volume was developed. Two variants of CFD models for calculating the working fluid parameters of the pulse tube refrigerator, the adequacy of CFD model based on experimental data were evaluated. The experimental setup of pulse tube refrigerator was designed and built to verify developed models and methods of numerical simulation of refrigerator, preliminary tests were conducted, the ways of improving the design of pulse tube refrigerator was determined.
