A three-dimensional, incompressible, viscous flow code, developed by NASA AMES (INS3D) using the pseudo-compressibility method, is modified for torque converter flow field computations. The code is used to predict the velocity and pressure fields in the pump of an automotive torque converter. Numerical results are compared to measured static pressure and velocity distributions. Results show that: (1) the code can fairly well predict the C{sub p} distribution, the distribution of the through-flow velocity, and the secondary flow field, (2) pump rotation has a major effect on the secondary flow field and on the mass-averaged total pressure loss, and (3) inlet velocity profiles have a profound effect on the mass-averaged total pressure loss.
