Abstract : The problem area of the interaction between the viscous and inviscid flowfields around a body is investigated. The study is based on ascertaining a flow model which has the ability of determining interaction effects wityout the possibility of having to choose between an infinite number of possible solutions. The importance of the inclusion of a two-family characteristic net for the outer supersonic flow and the normal momentum for the inner viscous flow is discussed and the necessity of their inclusion in order to have a properly posed model is presented. A result of the numerical analysis based on the flow model is presented and the uniqueness of such results is discussed.
