Abstract: 
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 helium at the cold end. Several features, such as a flat temperature region in the low temperature regenerator and increased mass flow rate at the cold end of this regenerator, are revealed. Effects of double-inlet operation and structure parameters of the 4 K regenerator are also analyzed. (C) 1997 Elsevier Science Ltd.
