ABSTRACT

In this paper, a multi-medium partial differential equation (PDE) model is established according to the temperature change data of the outer skin of the dummy in the thermal effect simulation experiment, considering the influence of density (ρ), specific heat capacity (C), thermal conductivity (λ), thickness (h) of different materials. In this paper, it is found that under certain conditions, the combination of Fourier law and the partial differential equation has a good effect on the heat conduction effect and temperature distribution in unsteady time. At the same time, while achieving the goal of thermal protection, it can reduce the cost and reduce the R & D cycle.
