Unsteady turbulent boundary layer interactions in high speed flows

Numerical Simulation of Heat Transfer in Chemically Reacting Shock Wave-Turbulent Boundary Layer Interactions

“…Notice that the density changes steadily toward vertical directions downstream of the slot for Downloaded by [Stanford University Libraries] at 06:00 07 October 2012 the case of frozen flow. However, for the case of reacting flow, there are considerable undulating trends due to formation of production species and the effect of dilatation and dissipation [5].…”

“…Notice that the idea behind this reassignment of implicitness parameters for the viscous terms is motivated by the need to alleviate stiffness caused by viscous boundary layers, particularly in turbulent flows, and diffusion boundary layers in chemically reacting flows. It can be shown that all currently available schemes (finite differences or finite elements) arise from some combinations of the proposed implicitness parameters [7). Substituting Eq.…”

“…A comparison of experimental measurements with a numerical analysis appears in the recent paper by Fujimori et al [4]. Chung and his coworkers [5][6][7] have studied finite element strategies as applied to shock wave-turbulent boundary layer interactions in reacting flows. The physical mechanism prevailing in air-breathing combustion in high-speed flows is enormously complex.…”
