Abstract
A multi-scale prediction method for an ablation behavior of a hypersonic aircraft heat resistant structure, includes inputting hypersonic inflow far field boundary conditions into a macro CFD solver to perform numerical simulation of the external flow field of a hypersonic aircraft; extracting the mass fraction and temperature distribution of wall surface components; obtaining an msd.txt file and an atomic path file recording the mean square displacement data through a micro RMD solver; obtaining the ratio of mass loss rate to material density, namely, the ablation retreating rate using the MSD method and Fick's law; inputting it into a CFD solver for performing grid reconstruction and transient calculation to obtain the transient variation in the external flow field of a hypersonic aircraft along the ablation retreating of the aircraft wall surface.
