摘要：

In this paper, the dynamic behaviour of the temperature profiles in the regenerator and in the gas near the hot and cold ends of the tube are discussed. The operation of a single-orifice pulse tube is described in general thermodynamical terms. This approach is extended to the double-inlet pulse tube. Expressions for the various sources of entropy are derived which lead to a relation for the coefficient of performance. It is determined when the second inlet improves the operation of the pulse tube and what are the optimum settings. (C) 1998 Elsevier Science Ltd. All rights reserved.
