Latest Patents

Dongsheng Wen holds a patent for a "Multi-scale method for high-temperature structure ablation prediction of hypersonic vehicles." This multi-scale prediction method involves inputting hypersonic inflow far field boundary conditions into a macro CFD solver to perform numerical simulations of the external flow field of a hypersonic aircraft. The process includes extracting the mass fraction and temperature distribution of wall surface components. Additionally, it obtains an msd.txt file and an atomic path file that records the mean square displacement data through a micro RMD solver. The method calculates the ratio of mass loss rate to material density, which is known as the ablation retreating rate, using the MSD method and Fick's law. This data is then inputted into a CFD solver for grid reconstruction and transient calculation, allowing for the analysis of transient variations in the external flow field of a hypersonic aircraft along the ablation retreating of the aircraft wall surface. He has 1 patent to his name.
