doi:10.16182/j.issn1004731x.joss.19-0558

Abstract

Abstract: In the traditional rectangular coordinate system, the human body characteristics can not match the differential equation. This leads to the low accuracy of the simulation results. Based on the geometric characteristics of the elliptic cylinder, the differential equation of the heat conduction is transformed from the rectangular coordinate system to the elliptic one, and the finite volume method of the alternating direction full implicit scheme pair is adopted. The improved heat conduction differential equation is applied to the simulation of the human body temperature. The simulation results, compared with the calculated values of the traditional differential equation and the measured ones, show that the method is correct and its calculation accuracy is high.

Key words: elliptic cylindrical coordinate system, finite volume method, thermal conductivity differential equation, human body characteristics, temperature distribution
