ABSTRAKT

Separation controlled flow over the hump is measured by using hot wire anemometry and computed by using Delayed Detached Eddy Simulation variant of SST k−ω model. Flow is controlled by using author's design of synthetic jet actuator. Vortex structures behind the hump are visualized. Results of the numerical computation using Ansys Fluent code and from the measurement are compared in the traversing plane behind the wall hump. Normalized deviation of measured velocity reaches its maxima close to the 60 % near the side walls.
