Predicting the Onset of Cavitation in Automotive Torque Converters—Part I: Designs with Geometric Similitude

Figure 7

Filtered SPL versus dimensionless stator torque for stall speed sweep of 40 RPM/s at 𝑝_𝑐=791 kPa, 𝑝_𝑏=584 kPa, and θ _in = 70^°C. Vertical dashed lines indicate onset of cavitation.
