Analysis of Temperature Distribution of Human Skin Tissue in Various Environmental Temperature with the Finite Volume Method

Abstract

The purpose of this study is to model and simulate the biological heat transfer of human skin tissue at various environmental temperatures, and to determine the temperature distribution of each layer of skin tissue. The purpose of this research is to model and simulate the onedimensional constant temperature distribution of human skin tissue at various environmental temperatures. The onedimensional steady-state biological heat transfer equation is solved by modifying the Pennes equation solved by FVM. In this study, the temperature distribution of the skin tissue was simulated with 5, 10, and 20 points of change. The FVM results are verified with Deng, Z.S.'s analysis results. The results show that it is successful to use FVM to model the onedimensional constant temperature distribution in human skin tissue, so the temperature distribution of skin tissue is often not analyzed under various environmental temperatures. When using Deng for FVM verification, the error rate of Z.S analysis results is only 0.9%, so the temperature distribution of skin tissue under various conditions is generally not analysed. Increasing the ambient temperature (25 to 34 °C) will increase the temperature of the skin's surface, making the gradient smaller. But this does not affect skin tissue damage, because it activates the body's metabolism.
