Boundary layer separation by a step in surface temperature (Q1205850)

The free-interaction influence of thermal expansion process in the boundary layer gas flow is analysed, using the formalism of the triple- deck theory. The physical model considered herein is the forced convection of a gas flowing over a flat plate subject to a step change in the surface temperature, taking place at a certain distance from the leading edge. Using finite-difference methods, the numerical results for the pressure, skin friction, thickness displacement and Nusselt number are presented.
