闭式循环热力发动机技术特点及应用研究

Research on Technical Characteristics and Application of Closed Cycle Heat Engine

概要介绍热力发动机的定义,及其相关分类方式。柴油机、燃气轮机和汽轮机等几类常见的热力发动机效率、结构及技术特点上的不同进行对比研究。介绍以闭式循环燃气轮机为代表的闭式循环热力发动机及其技术特点与应用。为进一步研究和选取柴油机、汪克尔发动机、斯特林发动机、汽轮机、燃气轮机,以及氦气轮机等机型,以对比研究的方式,得出热力发动机实现闭式循环及实现自行启动的特点,并针对其未来发展进行展望。

Firstly, the definition of heat engine and its related classification methods are briefly introduced. Secondly, starting from several common heat engines such as diesel engine, gas turbine and steam turbine, a comparative study is carried out on the differences in their efficiency, structure and technical characteristics.Then, the models represented by closed cycle gas turbines and their technical characteristics and applications are introduced in detail. In order to further study, the diesel engine, Wankel engine, Stirling engine, steam turbine, gas turbine, helium turbine and other models were selected, and the characteristics of closed cycle and self-starting of thermal engine were obtained by way of comparative study. And look forward to its future development.
