ESTIMATION OF TEMPERATURE-DEPENDANT THERMAL CONDUCTIVITY OF MATERIAL WITH GENETIC ALGORITHM
Q. Wei-qi¹, Z. Yu¹; ¹CARDC, China
To estimate the temperature-dependant function of thermal conductivity of the structural material of flight vehicles, an inverse method based on Genetic Algorithm to optimize the thermal conductivities at different temperatures from measurement was developed. Especially, some physical constraints are considered in optimization. The simulation results show that the estimation method is feasible.
