同时具有泄漏和热传递过程的Stirling热力循环分析

在实际的Stirling热力循环过程中,往往同时有泄漏和热传递.而对于这方面的研究,通常只注意到泄漏量的本身,而未涉及到泄漏对热力循环过程的影响.本文根据变质量系统热力学理论,提出同时有泄漏和热传递的Stirling热力循环的过程指数及其计算方法.该方法较好地反映了实际的Stirling热力循环过程,而且计算简便,对研究和设计Stirling循环发动机提供了理论依据.

The Analysis of Stirling Thermodynamic Cycle with Leakage and Heat-transferring Path

There usually are leakage and heat-transferring together in an actual Stirling thermodynamic cycle path. Researchers in this field only noticed leakage amount itself, but paid no attention to the effects of leakage and heat-transferring to thermodynamic path. In this paper,a path exponent of Stirling thermodynamic cycle which possesses both leakage and heat-transferring and the computational method of this exponent are proposed according to the varying mass system thermodymamic theroy. This method is very well in reflecting the actual Stirling thermodynamic cycle,is convenient in calculating and offers a theoretical basis for the studying and designing of Stirling cycle engines.
