Abstract
By means of a single-tube set-up, the influence of some factors, i.e.relative depth of jet hole in the gas distribution ( b/d) , interval distance between oscillatory tube and jet hole (δ) and misalignment angles between the central axises of nozzle and oscillatory tube (ψ) , on performance of pressure wave refrigerator were studied exper-imentally in this paper.In this experiment, the range of pressure ratioε=2~6, relative length of the oscillatory tube L/d=437.5 and jet flow pulsing frequency f=10~240Hz.The results showed that refrigeration efficiency of the pres-sure wave refrigerator (η) was firstly increased and then decreased when b/d was increased, but increasingδandψwould causeηsudden drop.Under the experimental condition in this paper, the recommend value of b/d was 0.5.关键词
