Supersonic triple deck flow past an eroding hump

The problem of laminar supersonic flow past an eroding hump is formulated on the basis of the triple deck theory. The resulting lower deck problem is intrinsically unsteady with a moving boundary, the hump surface. Numerical solutions are obtained, starting from a steady hump flow till the hump and its contamination particles are totally removed from the computational domain. Typical results are presented; showing how the erosion of the hump progresses, and how the contamination spreads. The effect of the Schmidt number is also studied. The results attest to the validity of the triple deck model as well as the numerical solution method.
