A two-dimensional, two-passage simulation of the relative flow through a transonic
fan at M = 1.4 was designed with a view to providing an apparatus in which to assess the
effectiveness of passive vortex generator techniques in alleviating shock-boundary layer
interaction effects. The design of the model and the results of six tests in the transonic
cascade blowdown wind tunnel are described. Schlieren photographs of the shock
structure were obtained at back pressures lower than the design value. The back-pressure
control valve was identified as being critical to completing the experimental simulation.
The flow through the cascade geometry was computed at design pressure ratio using an
Euler code. Modifications to the grid are recommended before thin-layer Navier-Stokes
calculations are performed.
