Abstract

The scramjet thermal environment was studied in this paper.The computational model for the scramjet thermal environment was established based on the two-dimensional N-S equation and one-dimensional Raleigh heating law.The simulation program was developed using MacCormark forecast-calibration scheme.Thermal environment of the scramjet with Mach 6 and Mach 8 was computed

the scramjet internal flow field temperature and wall heat flux distribution were gained.The analysis of the results shows that the combination of 2D no reaction flow field calculation and 1D heating law of the thermal environment research of scramjets are feasible and effective.
