In this study, the aerodynamic heating of the flying body during powered flight phase has been numerically investigated. The conjugate simulation of fluid heat transfer and solid heat conduction has been considered. To this aim, the coupling boundary condition has been used for body shell that allows the conjugate heat transfer investigation in the fluid and solid domains simultaneously. The model has been considered as a circular cylinder and spherically blunted cone nose with 350mm in diameter. The investigation has been carried out at different Mach number from 1.5 to 4.2 to cover range of supersonic flow. The advantage of this method is that the wall temperature and heat flux ââin any part of the nose and body shell with or without axial symmetry, connected components and other protuberances could be calculated at different angles of attack. Finally, the approach has been validated through the results of analytical and numerical methods for aerodynamic heating of axisymmetric vehicles.
