OS11-3 Effects of heat storage material on pulse tube engine performance

Abstract

Stri1ing engines have t血e composition of 2 pistons in 2 cylinders or 2 pistons in l cylinder except fbr a double acting type engine ． Heater ， fegenerator and cooler are insIalled betWeen 2 plstons ． The pulse tube engine consists of l piston 正 n l cyl 量 nder ， pulse tube ， heateiregenerato ら cqoler and 2nd cooleL In血 is papeら in order to investigate 出 e basic characterist 玉 cs ofthe pulse tube gine， an ep ． gine of simple eompositio4 which used atmospher 孟 c pressure air as the working gas， has been manufactured ． Gas parcels are observed to flow out of the heater in pulse tube using LDV ． Th ¢ measurements of the worldng gas behavior in 丗［ ermoacoustic oscillation in pulse tUbe are inv巳stigated ， Based on the resul ち e ｛ fectS of heat storage rnaterial in pulse tUbe on shaft power and indlcateCl power are examined experimenta 】 1y As one of 血 e performance improvemeng the excellcnt effect of regenerator in pulse tube has ． been confirmcd ． Key"・ordS ： energy cenversion ， thermoacoustics ， standing wave ， heat engine ， shafi pQwer
