Theoretical determination of thermal diffusivity of composite material
摘要
A very simple model based on the Quadrupole method was used in the theoretical analysis of thermal diffusivity of composite materials of Cu-PVC, PVC-Cu-PVC, and Cu-PVC-Cu. The use of MATLAB software with a return to real space using the Stehfest algorithm makes the time of calculation very short. The thermal responses on the rear face of each considered sample, which determine the thermal diffusivity were represented. A mathematical demonstration which confirmed the results was given. Thermal diffusivity determined from the rear face thermal responses were compared with the results of the thermal diffusivity calculated by considering the composite materials to be homogeneous, and a discussion on the two kinds of results was provided.
