Book Description
Mathematical expressions for the boundary conditions of longitudinally slotted walls are derived in order to facilitate calculations to determine the effectiveness of slotted walls in wind tunnels. A relationship is first established for the effect of flow curvature on the boundary conditions in the vicinity of conventional slotted walls for incompressible flow. This relationship is then extended to include the influences of protruding slats as well as of perforated cover plates at the base of the slots. Finally the extent to which the derived equations are valid for compressible flow in the subsonic and supersonic speed range is shown.
