Abstract: According to analysis of physical property of heat transfer oil sample data, using method of mathematical model, the parameters of the physical property were calculated by regression algorithm, and in range of set allowed variance, the parameters of the mathematical model were obtained. The calculation result was compared with the physical property calculation result in original database, and the comparison shows that to adopt the physical parameters based on the sample data regression can improve the calculation precision and perfect the engineering design.
