An efficient numerical solver for the two-dimensional supersonic interacting boundary layer equations
is constructed. It is a two-sweep iterative approach that converges fast with the use of an enhancing
parameter. It uses variable step sizes in both the streamwise and lateral directions, in order to
accommodate regions of fast changes. It adopts a layout of the flow variables and a second order
accurate finite difference representation that allow non-iterative streamwise marching and require the
storage of streamwise variables only. The solver is applied to the compression corner problem; when
the corner is sharp producing a sizable separation bubble, and when the corner is augmented to prevent
separation. Comparisons with corresponding asymptotic triple deck results are presented.
