THEORETICAL ANALYSES AND EXPERIMENTAL INVESTIGATION OF GASSTREAM WAVE REFRIGERATION IN THE PRESSURE PULSE TUBESOFAROTATINGHEATSEPARATOR JianfengWang RefrigerationLaboratory,EngineeringThermoscience Department,Zhejiang University,Hangzhou,P.R.

Many experiments on the RHS are made on different ongineering operating conditions in order to prove the the reliabiiity of theoretical analyses.The saddle form wall temperature.distributionof the PPTs and pressure pulse curves of the gases with optimal matching andnon-optimal matching are obtained
