Taking the computation of three dimensional flow field in the hydraulic torque converter as an investigation subject, a cubic spline interpolation function is used to solve velocity distribution in the flow field. And the rates of the change of the velocity components with respect to the flow surfaces are derived, then the tendency of the change of the velocity is also derived. This method is more precise and the computational results coincide with the real flow field. So this method will be more valuable in the flow field computation of all turbomachines.
