摘要/Abstract

摘要： 为研究导叶可调式液力变矩器的内部流动特性，以循环圆直径为320mm导叶可调式液力变矩器作为研究对象.采用计算流体动力学(CFD)方法对其不同开度、不同工况下的内部流动状态进行数值模拟，并对相应的透明模型进行粒子跟踪测速(PTV)试验验证.同一开度下，随着转速比的增加，可调导轮内部液流速度增加，液流方向与叶片进口方向的夹角增大；在制动工况时，叶片工作面有漩涡现象，而空载工况时，叶片非工作面有漩涡产生.对比试验与数值模拟内流场结果，发现后者可以比较准确地预测导叶可调式液力变矩器的内部流动特性.该结论为研究导叶可调式液力变矩器内部流动状态，预测外特性及其设计优化提供了方法和依据.

Abstract: In order to study the internal flow characteristics of a hydrodynamic torque converter with adjustable guide vanes， the hydrodynamic torque converter with 320mm circular diameter was selected as the research subject. The computational fluid dynamics (CFD) method was applied to calculate the internal fluid flows at different openings and working conditions. Meanwhile， a prototype made by plexiglass was tested by PTV. Then， the internal flows were both obtained using CFD and PTV. Under the same opening， the flow velocity increased with the speed ratio， and the angle between the flow direction and the inlet angle direction of the adjustable guide vane increased as well. In the stall condition， the vortex phenomenon was observed near the vane’s working surface. However， at the no-load condition， the vortex phenomenon emerged in the vane’s non-working surface. The results showed that the numerical simulation method can perform a comparatively accurate prediction of the internal flow characteristics of the hydrodynamic torque converter with adjustable guide vanes in comparison with the test， which can provide a method and basis for the research on its internal flow state， and the performance prediction and design optimization of the hydrodynamic torque converter with adjustable guide vanes.

Key words: hydrodynamic torque converter with adjustable guide vanes, internal flow field, working condition, opening, CFD (computational fluid dynamics), PTV (particle tracking velocimetry)
