【Abstract】 Based on the theoretical analysis we have made experiments on the performance of the pulse tube driven by thermoacoustic prime mover with mixture working gases.The experimental results have indicated that the refrigeration performance of the pulse tube have been improved as the Prandtl number of the helium argon declines.更多还原
