Heat transfer for high temperature operation based on ANSYS thermal analysis

Mainly consider the heat conduction between the layers of fabric, the thermal convection between the fabric and the air to establish the model of this paper. Firstly, the heat conduction equation between multilayer fabrics is constructed by the law of conservation of energy and Fourier’s law; then, the heat convection equation between the fabric and the air is expressed by Newton’s cooling formula; Finally, the thermal conductivity, temperature boundary conditions and temperature load between the fabrics of each layer were determined, and a heat transfer model conforming to the external environment—fabric (I∼III)—air layer—human skin system was established. Considering the wide application of finite element in heat transfer, we use ANSYS heat transfer module to calculate the temperature distribution of each layer of the system by using transient thermal analysis method. The simulation results are well fitted to the actual experimental results, and the temperature of each layer is generated.
