ABSTRACT

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.
