In calculations of transonic flows it is necessary to limit the domain of computation to a size that is manageable by computers. At the boundary of the computational domain, boundary conditions are required to ensure a unique solution. Since wave solutions exist in the unsteady transonic flow field,
An integral equation method based on the full-potential equation for transonic flow calculations is presented. The full-potential equation is written in the moving frame of reference, in the form of the Poisson's equation. The integral equation solution in terms of the velocity field is obtained by
This paper presents a parallel multigrid method for computing inviscid and viscous high speed steady-state reactive flows. The governing equations for reactive flow are solved using an explicit multigrid algorithm while treating the chemical source terms in a point implicit manner. The CUSP (Convect
