摘要 为研究涡旋膨胀机的性能并对其进行理论和实验分析,基于能量和质量平衡建立了热力学模型,在热力学模型中考虑了径向和切向泄漏,工质气体、涡旋盘和板之间的传热。通过求解热力学模型,得到了工作容积、压力、工作腔质量流量和功率。最后搭建了一个简单的涡旋膨胀机性能测试实验台。通过仿真和实测数据的比较,验证了所建立的热力学模型能够准确地描述涡旋膨胀机的整个进气、膨胀和排气过程。 In order to investigate the performance of the scroll expander and conduct theoretical and experimental analysis, a thermodynamic model was established based on the energy and mass balance. Radial and flank leakage, heat transfer between the working fluid, scroll wraps and plates were considered in the thermodynamic modeling. Volume, pressure, mass flow of working chamber and power were investigated by solving the thermodynamic modeling. A simple experimental rig for scroll expander was set up. From the comparison of the simulated and measured data, it could be seen that the proposed thermodynamic modeling could accurately describe all the suction, expansion and discharge processes for scroll ex- pander.
