摘要

摘要: 限矩型液力偶合器的工作状态始终是部分充液，内部气—液两相流体介质在泵轮流道和涡轮流道之间做螺旋环流运动。以YOX500液力偶合器为研究对象，利用CFD（Computational fluid dynamics）软件中的滑移网格法与流体体积法VOF（Volume of fluid）对液力偶合器内部流场进行瞬态分析，得到了液力偶合器内部两相、速度、压力分布，总结了其流场结构的变化与规律。同时对其外特性进行计算，将模拟结果与实验结果进行比较分析，对所使用的CFD数值计算方法的有效性进行评价，为液力偶合器内部流道的设计和优化提供方法。

Abstract: The working conditions of the torque-limited hydrodynamic coupling are always partially filled with liquid, and the internal gas-liquid two-phase flow medium spirally circulates around pump channel and turbine channel. To study the YOX500 hydrodynamic coupling, the transient analysis of the internal flow field of the hydrodynamic coupling is carried out with the sliding grid method and the volume of fluid in the CFD (computational fluid dynamics) software. The changes and rules of its flow field structure are simulated in terms of its two phases, velocity and pressure distribution inside the hydrodynamic coupling. The external characteristics of the hydrodynamic coupling are also calculated and compared with the experimental results. The effectiveness of the CFD numerical calculation method is evaluated, providing a method for the design and optimization of the internal flow passage of the hydrodynamic coupling.
