Abstract: On the basis of the principle of boundary layer control, this paper discusses the wind channel test of a tandem blade cascade of stator in liquid torque converter, analyzes the flow less mechanism and characteristics of the tandem and compares them with those in single blade cascade. The flow field within the tandem cascade and boundary layer parameters on the blade surface are calculated on the blade-to-blade surface. The analytical result of theory calculations and tests show that the application of tandem cascade provided a hopefull way to increase the efficiency of liquid torque converter remarkably.
