An implicit Navier-Stokes solver for two-dimensional transonic shock wave-boundary layer interaction
A code has been developed using an implicit numerical scheme for solving the two-dimensional unsteady Navier-Stokes equations for the transonic shock wave-boundary layer interaction problem. The method is an adaptation of the implicit MacCormack scheme for viscous compressible flows. The technique is illustrated by applying it to study the flow past an 18 \% symmetric circular arc airfoil. A coordinate transformation is made use of to facilitate direct application of the method. Numerical results obtained through the software, for surface pressure distribution and skin friction exhibit reasonable agreement with those got earlier by \textit{G. S. Deiwert} [AIAA J. 13 (1975), 1355-1359 (1976; Zbl 0318.76042)] using an explicit integral scheme.
