Abstract
A dynamic experimental apparatus has been constructed to investigate the instantaneous velocity and pressure in the multi-bypass pulse tube refrigerator(MPTR). Some important experimental results of the instantaneous measurements of the velocity and the pressure in the MPTR with two-bypass tubes during actual operation are presented. The effects of the middle-bypass version on the dynamic pressure and mass flow rate at the cold end of the pulse tube are evaluated from experimental measurements. DC-flow phenomena are observed in this MPTR. The reasons of the multi-bypass version improved the performance of pulse tube refrigerator are given.
