A computational and experimental study on the flow around the strut-plate juncture with zero and 5゜ angle of attack is presented to make clear its flow characteristics. The separation lines on the surface of the plate and the strut being visualized, the flows are simulated by solving the Navier-Stokes equations for the two Reynolds numbers, 10^3 and 10^4. The computational results seem to agree with the visualized flows qualitatively. Characteristics of the junction flow are discussed by making use of the computational results. It is made clear that the effects of the Reynolds number and the angle of attack on the flow are noticeable. The estimated pressure and skin friction on the strut showed a strong three-dimensionality in spanwise. It can be concluded that such numerical studies can be an effective tool for the study of complicated flow.
