| Abstract: | In the present paper the factors,the length of oscillating tube,the rotary velocity of the gas distributor and the gas expansion ratio,which affect the isentropic efficiency of gas wave refrigerator were studied experimentally The curves for the factors affecting the isentropic efficiency are presented and analyzed The ways to increase the isentropic efficiency by exhancing the heat transfer outside the oscillating tubes or coupling with the structure of pulse tube refrigerator were studied experimentally The results are very important to perfect the structure and performances of gas wave refrigerator |
