ShareIsothermal model of pulse tube refrigerator.
Author(s) : ZHU S. W., CHEN Z. Q.
Type of article: Article
Summary
The main assumptions of the isothermal model are that the gas in the middle part of the pulse tube is adiabatic and the gas in the other parts is isothermal. The results from the isothermal model are compared with those of the nodal analysis. The gross refrigeration power and the input power using the former are about 20% lower than values obtained using the latter. The pressure ratio and the average mass flow rate are about 5% lower using the isothermal model.
