由于热回收循环中包含大量潜在的工作流体，因此所需涡轮机的空气动力学设计和性能存在一定程度的不确定性。本文旨在探讨跨音速涡轮的气动性能的一般方式，使准确的预测涡轮机性能可以为各种工作流体。在这项研究中，一个热力学的方法来模拟一个通用的工作流体的基础上彭罗宾逊状态方程。将该模型与计算流体动力学相结合，系统地研究了各种流体参数对涡轮机气动性能的影响。因此，这项工作提出了一个适用于任何跨音速蒸汽涡轮机的涡轮机损失模型的步骤。
Due to the vast number of potential working fluids incorporated within heat recovery cycles, there is a degree of uncertainty around the aerodynamic design and performance of the required turbomachinery. This paper aims to explore the aerodynamic performance of transonic turbines in a generic manner so that the accurate prediction of turbine performance can be made for a wide variety of working fluids. Within this study, a thermodynamic approach to model a generic working fluid is presented based on the Peng-Robinson equation of state. This model is used in combination with Computational Fluid Dynamics to complete a systematic study into how various fluid parameters impact turbine aerodynamic performance. Therefore, this work presents a step towards a turbine loss model which is applicable to any transonic vapour turbine.
