Abstract:
An artificial heat source（AHS） method is proposed to solve the problem of negative volume or non-physical property errors that happens in the process of heat transfer simulation of the aircraft electro-thermal windshield which has a thin film heater embodied in its multilayer structure. Since the thickness of the thin film heater is very small （10-9—10-7 m），the temperature gradient between the film heaters and the time delay generated by heating the film heater can be ignored， and the thermal diffusivity can be set to infinity for decoupling the thickness relationship between the real heat source and the mesh model in the simulation. Heat transfer simulations are conducted on the aircraft electro-thermal windshield mesh models with different thicknesses of the film heater. The results show that with the AHS method， mesh thicknesses of the thin film heater has no influence on the results of the simulation， and the problem of negative volume or non-physical property errors is solved spontaneously.
