Numerical Simulation of Dominating Control Factors of Thermal Protection FGM’s Effective Thermal Conductivity

Abstract:

Thermo-shock resistance of the thermal protection materials is affected by its heat, mechanical properties, and various environmental factors. Therefore, it is very essential to understand which factors take great roles in affecting thermo-shock resistance and how much they affect, when designing the thermal protection materials. This paper applies the experimental scheme designed by means of orthogonal design and implement numerical experiments with the numerical simulation technology; and analyses the factors which affect the thermo-shock resistance of FGM material, such as choice of ceramic material, specimen thickness, number of layers, and heat flux loading; then identifies the dominating factors controlling the thermal shock resistance of thermal protection materials.
