Abstract
The effect of axisymmetric diffuser wall rotation was experimental studied. Diffuser with an apex angle of 30 degrees was investigated by PIV method on Re number from 9 000 to 44 000 and the angular velocity from 0 to 3000 rpm. POD method was used for no stationary flow description. The study showed that rotating diffuser walls leads to expansion of the air flow at the output, and can be viewed as a method to increase their effectiveness.
