在本文中，我们研究了有机朗肯循环 (ORC) 涡轮机内发生的真实气流。讨论了一种设计稠密气体喷嘴的新方法，并将其应用于高压比涡轮叶片的情况。然后，将使用 ORC 涡轮机典型的各种工作流体的状态方程的纳维-斯托克斯方法应用于涡轮机叶片，以确定叶片性能。结果表明，工作流体的选择对涡轮机效率有显着影响。
In this paper we investigate the real gas flows which occur within Organic Rankine Cycle (ORC) turbines. A new method for the design of nozzles operating with dense gases is discussed, and applied to the case of a high pressure ratio turbine vane. A Navier-Stokes method which uses equations of states for a variety of working fluids typical of ORC turbines is then applied to the turbine vanes to determine the vane performance. The results suggest that the choice of working fluid has a significant influence on the turbine efficiency.
