| 摘 要： | 本文提出了五部件绝热气缸模型。考虑热交换器的效率及其死容积的影响,运用变质量系统热力学理论和数值方法,分析了现代实用的斯特林循环,求出循环内各热参数的瞬时变化和一个循环的平均参数。在实验室的试验机上,进行了机内动态参数的直接测定。理论分析和实验研究表明,本模型和方法比目前常用的经典等温模型更切合实际,可推荐作为热力设计计算的基础。

| Abstract: | A five-piece model with two adiabatic cylinders for analyzing stirling cycleis proposed in the paper. In the model there are considered thc temperature effi-ciency and the effect of void volume on the gas flow for each heat exchanger.Using thermodynamics of variable mass systems and numerical method, theinstantaneous and average parameters in the cycle can be calculated. This paperpresents some experimental results obtained on a test stirling engine in ourlab. Theoretical analysis and the test results show that the model proposed inthis paper can have better prospects than the classical isothermal model so farjused. |
