Coupled radiating shock layers with finite rate chemistry effects. Part 2: Analysis of the interaction of ablating protection systems and stagnation region heating
Abstract
The conservation equations that describe the mass, momentum, and energy transfer in the shock layer around an ablating blunt body were developed and placed into numerical solution form. Effects of line and continuum radiation along with finite rate chemistry were considered. Sixteen chemical reactions with 19 chemical species were included in the analysis, and 12 of these species were employed in a radiative flux divergence calculation. The shock layer was coupled to a phenolicnylon charring ablator through a surface energy balance. Results show that the numerical solution of the quasilinearized conservation equations yields stable and accurate solutions to the nonequilibbrium, radiating shock layer surrounding a blunt reentry body.
