© 1999 American Institute of Aeronautics & Astronautics. Many aerodynamic flow control devices make use of wall transpiration as a means of influencing boundary-layer behavior. The use of drilled-hole plates has come to be preferred for this purpose. To evaluate the aerodynamic performance of such plates in either a real physical system or its CFD-modeled simulation, it is crucial to have an accurate knowledge of how the mass flow through the plate hole depends on the driving pressured difference across the plate as a function of the relevant parameters such as hole diameter, plate thickness and the properties of the gas. This paper offers a new unified theoretical model of viscous compressible flow across a hole which gives the designer or numerical analyst of transpiration systems the ability to conveniently predict the characteristics of a porous plate a priori for any given flow conditions. Validating comparisons with experimental data are also Presented.
