A Study on Juncture Flows

A computational study of the flow around the strut-plate juncture formed by the inclined strut and curved plate is presented. The characteristics of the flow are discussed by making use of the solution of the Navier-Stokes equations. To investigate the effects of the inclination angle of the strut and the curvature of the plate on the juncture flows, the computation has been made for three different inclination angles of strut and two different curvature of plate. The flow structure is changed greatly due to the inclination of strut and the forces acting on strut are affected greatly by the inclination angle. However the effects of the curvature of plate on the flow and the forces acting on strut are less than thoes of inclined cases. Although the plate is curved, the local angle is still 90° and it can be concluded that the local angle between strut and plate will be an important parameter for the flow structure around a juncture.
