Abstract:

The Aerotherm BLIMP Boundary Layer Integral Matrix Procedure boundary-layer code provides numerical solutions of the nonsimilar, multicomponent, laminar or turbulent boundary layer with equilibrium or nonequilibrium chemical systems, unequal diffusion and thermal diffusion coefficients for all species, and a variety of surface boundary conditions including intimate coupling with transient charring - ablation energy and mass balances. Numerous comparisons have been made of BLIMP boundary-layer calculations with results from other computation schemes and with experimental data. The objective of this report is to make further comparisons at conditions more appropriate to the early portion of a reentry flight 150,000 to 100,000 ft, that is, at altitudes still high enough that ablation and shape change are not important, but low enough that low density effects are also not important.
