• A numerical study on the turbulent flow around the strut-plate juncture is carried out for the inclined strut and for the flow with an angle of attack. Computations are made by solving three-dimensional incompressible Reynolds-averaged Navier-Stokes equation with MAC method. Turbulence is simulated by using Baldwin-Lomax model with a modified length scale for the treatment of corner flow. The flows, at the Reynolds number of 10^5, show intensive unsteady behavior near the plate while the flows are steady enough off the plate. Inclination of the strut induces a lift which is generated mainly near the plate. On the other hand, the lift by an angle of attack reduces near the plate.
