摘要

In this paper, effects of different operating conditions on amplitudes of the dynamic pressure and mass flow rate and phase shift between them at the cold-end of the regenerator under high frequency oscillating flow are studied in details. The instantaneous velocity at the outlet-end of the regenerator is obtained by using a hot wire anemometer. The results show that there are optimal values for orifice settings, operating frequencies, mean pressures, and pressure ratios to improve the refrigeration performance of high frequency pulse tube refrigerators. The reasons of the optimal value existed are discussed.
