Abstract

A wind tunnel was designed by the author for studying the aerodynamic properties of porous plates; it was constructed and installed in the Heat Power Laboratory, Mechanical Engineering, South Dakota State University. With a total pressure tube, the velocity profile throughout the boundary layer and the average shear stress at the wall were determined. A Preston tube was used to measure-local shear stress. There are only limited experimental data available on the relation between roughness and shear stress for flow over porous surfaces with injection or suction. Because of instrumentation problems, it proved difficult to obtain data in the sublayer. Nevertheless, the present study can be considered to be a first step toward further investigations into problems of this type.
