Experimental study of air flow in axisymmetric diffuser output section with rotating wall

Kurkin E.I., Ivchenko A.V.

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.

Redkina K.V., Frolov V.A.

Abstract

A model of a stationary vortex for the potential circulation flow around airfoil-spoiler combination has been proposed. The solution is obtained for the flow of incompressible ideal fluid. The Complex Variable Function Theory is applied. For the simulation of the recirculation area, a stationary vortex is used, the location of which is found by minimizing a velocity function. Dependence of the lift on the angle of attack, relative length of the spoiler and its angle of deflection is obtained.
