To account for rarefaction effects and real-gas nonequilibrium in weakly ionized air, a finite-volume method coupling the multicomponent nonlinear coupled constitutive relation (NCCR) with MHD source terms is developed under low-magnetic-Reynolds-number approximation. The NCCR model replaces conventional Navier–Stokes–Fourier linear closure for stress and heat flux, while Park’s two-temperature model and a multi-species finite-rate air mechanism describe thermochemical nonequilibrium. Numerical results show that MHD thermal-protection performance is governed not only by magnetic-field strength, but also by shock-layer ionization, current localization, and heat-load redistribution over the forebody.
