Key Points
Radiative heating accounts for 70% of the total heat flux at Mach 45, highlighting its significance.
Coupled simulations show a 12% decrease in convective heat flux, emphasizing the importance of accounting for interactions.
Decoupled calculations lead to overestimation of total heat flux in high-speed scenarios, stressing the need for accurate modeling.
Validation against FIRE II flight data establishes the reliability of the coupled flowfield-radiation numerical method.
