In the field of clean energy, Organic Rankine Cycle (ORC) is considered a vital method to utilize low-grade waste heat effectively. Due to certain application advantages in low power level ORC systems, the Tesla turbine is considered one of the essential choices for the core components of ORC systems. Given the inadequacy of the current research on the performance of the Tesla turbine under two-phase flow conditions, a one-dimensional model of the Tesla turbine was constructed in this paper to make it equally applicable to the two-phase flow conditions of wet working fluids. A model of the Tesla turbine and ORC system was constructed from the thermodynamic point of view, and five typical wet working fluids (R22, R417a, R134a, R152a, and R290) were selected to study the effects of the five wet working fluids on the thermal performance of Tesla turbine and ORC system. The effects of the changes in key structural parameters of the Tesla turbine on the performance of the Tesla turbine and the ORC system were further analyzed when different wet working fluids were used in the ORC system. The results showed that the highest turbine efficiency of 42.0 % was achieved when the Tesla turbine used R22 as the working fluid under the design conditions, while the highest turbine output power and the highest system thermal efficiency of 1.19 kW and 3.96 % were achieved when R417a was used as the working fluid. The analysis of the key structural parameters of the system showed that for the five different wet working fluids, the turbine efficiency, turbine output power, and system thermal efficiency increased monotonically with increasing rotor inlet radius. For each of the five wet working fluids, an optimum rotor speed, rotor outlet radius, and rotor gap distance exist, resulting in optimal turbine efficiency and system performance. The related work provides an important reference for the optimal design of Tesla turbines with wet working fluids.

在清洁能源领域，有机朗肯循环（ORC）被认为是有效利用低品位余热的重要方法。由于在低功率级ORC系统中具有一定的应用优势，特斯拉涡轮机被认为是ORC系统核心部件的必备选择之一。鉴于目前对两相流条件下特斯拉涡轮机性能研究的不足，本文构建了特斯拉涡轮机的一维模型，使其同样适用于湿作业的两相流条件。流体。从热力学的角度构建了特斯拉涡轮机和ORC系统的模型，以及五种典型的湿式工作流体（R22、R417a、R134a、R152a、和 R290）被用来研究五种湿式工质对特斯拉涡轮机和 ORC 系统热性能的影响。进一步分析了在ORC系统中采用不同的湿工质时，特斯拉涡轮机关键结构参数的变化对特斯拉涡轮机和ORC系统性能的影响。结果表明，在设计工况下，特斯拉涡轮机使用R22作为工质时，涡轮机效率最高达到42.0%，而R417a时涡轮机输出功率最高，系统热效率最高，达到1.19kW和3.96%。被用作工作流体。系统关键结构参数分析表明，对于五种不同的湿工质，涡轮效率、涡轮输出功率、系统热效率随着转子入口半径的增加而单调增加。对于五种湿工作流体中的每一种，都存在最佳转子速度、转子出口半径和转子间隙距离，从而实现最佳涡轮效率和系统性能。相关工作为采用湿工质的特斯拉涡轮机的优化设计提供了重要参考。
