【Abstract】 Taking the computation of the three-dimensional flow-field in hydrodynamic torque-converter as an investigation subject, an approximate method based on the theory of a couple of relative flow-surfaces is brought forward. The mathematic equations are derived, the computational method and solution procedure are given in this article. Subsequently, the three-dimensional flow-field of the type of hydrodynamic torque-converter, YB355-2, is calculated. The results of computation and test are compared and analyzed. The computational results agree well with the measured. So this method is more precise and will be more valuable in the flow-field computation of all the turbomachines.更多还原
