Abstract

Abstract

In order to study the gas-liquid two-phase distribution and the torque characteristics of the torque limited hydrodynamic coupling, the YOX500 torque limited hydrodynamic coupling is used as the analysis model. The VOF two-phase flow model, the realizable k-ε turbulence model and the PISO algorithm are used to perform the transient simulations of the internal flow field of the hydrodynamiccoupling under different filling rates and different working conditions. The results show that as the speed ratio decreases, the internal circulation of the hydrodynamiccoupling gradually changes from a small circulation to a large one. Under the condition of 80% filling rate, the gas-liquid two-phase distribution to the suction surface and pressure surface of the impeller blade is basically consistent with the experimental results, thus proving the effectiveness of the method. At a high-speed ratio, the torque characteristics are consistent with the experimental results. At a low speed ratio, the error is large; therefore the method is no longer applicable.
