Coupled Numerical Study on Aeroheating, Radiative Heat Transfer and Structure Heat Conduction for Hypersonic Bodies of Revolution

An integrated fluid-thermal-structural coupled simulation in which the aeroheating, radiative heat transfer and structure heat conduction were worked together, and everyone was provided a boundary condition for others was adopted to study the flow fluid and temperature fluid brought by these aerodynamic heats of the hypersonic bodies of revolution in this paper. The out flow field of the bodies and unsteady process of the boundary temperature were numerical simulated. The results showed that this method dynamically could simulate the objective physical processes of the flow fluid and the temperature fluid.
