Numerical Simulation of Temperature Field of Thermal Insulation Coating during Heat Transfer Process
The finite difference model of reflective thermal insulation coating was established,and a numerical simula-tion algorithm of two-dimensional temperature field and ellipse interpolation algorithm of three-dimensional tempera-ture field for the heat transfer process of the coating were proposed.A simulation software to predict thermal insulation performances of coating was developed based on Qt application development framework and CPU parallel acceleration.On this basis,the temperature field of coated and uncoated substrates was calculated,and effects of coating on tempera-ture rise rate and final temperature of substrate were obtained,verifying the adaptability and reliability of the software.
