Static pressure measurements and cavitation signatures on the nose of a torque converters stator blades

Test Apparatus. The experimental stator was designed with fifteen 0.5 mm diameter pressure taps situated in a 3x5 array that wrapped around the nose of the stator. These locations coincided with where the CFD model had predicted a “zero pressure” region to occur. Fig. 5 shows one stator blade and an expanded view of the stator nose showing the location of the pressure taps. The actual stator had only one pressure tap per blade. Each row spanning across the blade from shell to core was given a station number. The station on the pressure side of the blade is called Pressure Station 1 (PS1) and those on the suction side of the blade are called Suction Stations (SS). Pressure taps were located at 0.25, 0.50, and 0.75 of the width of the blade from the shell to the core (S-C). A station number and a shell to core position denote the location of each pressure tap.
