In this paper, the static pressure field and performance parameters of a torque converter pump are measured, analyzed, and interpreted under three turbine/pump speed ratio conditions (0, 0.6, and 0.8). A potential flow code is used to predict the static pressure distribution. Results show that: (1) centrifugal force has a dominant effect on the static pressure rise in the pump; (2) the static pressure field is generally poor at the core section; and (3) the potential flow code can fairly well predict the static pressure distribution at the blade mid-span, but not at the core and shell sections.
