✦ Synopsis

A computer program for numerical simulation of 4 K pulse tube coolers has been developed which takes into account non-ideal gas properties of 4He, the properties of the magnetic regenerative material, and the heat transfer in the heat exchanger and regenerator. The presented modelling is very efficient for visualizing physical processes in 4 K pulse tube coolers. The numerical predictions are compared with the performance of existing pulse tube coolers for liquid helium temperature and are found to be in reasonable agreement.

The processes and performance of two configurations of 4 K pulse tube coolers and a G-M cooler are analyzed by numerical simulation. A configuration of the pulse tube cooler where the phase shifter is located at room temperature does not lead to an efficient phase shifting of the moving liquid heliu
