MEASUREMENT AND ANALYSIS OF STATIC PRESSURE FIELD IN A TORQUE CONVERTER TURBINE

In this paper, the static pressure field and performance parameters of a torque converter turbine are measured analyzed, and interpreted und er three speed ratio conditions (0, 0.6, and 0.8). A proven measuremen t technique was developed for the steady-state measurement of static p ressures in the turbine. Results show that: 1) the static pressure fie ld is generally poor at the core section; 2) centrifugal force has the dominant effect on the static pressure drop in the turbine at SR = 0. 6 and SR = 0.8; and 3) the static pressure loss due to viscous effects and due to the diffusion of the relative velocity is very pronounced at SR = 0.
