摘要
根据物理上直观的拉格朗日法 ,分析了交变流动发动机中回热器内代表性气体微团的热力过程和循环。分析表明 ,回热器中的每个气体微团都是一个功能完整的微型发动机 ,只不过它们工作在不同温度水平。在回热器中 ,微团通过接力作用 ,逐步将高温热源的热量转换为声功 ,并将不能转换的热能排向环境温度热源。
The thermodynamic processes and cycles of some characteristic gas parcels in the regenerator in a cyclic flow engine are analyzed thoroughly in Lagrangian’s view. The analysis clearly reveal that every gas parcel in the regenerator works as a micro prime mover at different temperature levels.For the regenerator of the prime mover, all gas parcels inside the regenerator work together and cooperate elegantly to transform the heat from the high temperature resource into mechanical power, meanwhile dissipating those useless heat to the surroundings.
