Abstract

In this work, Finite Element Method (FEM) is employed to solve the problem of two-dimensional heat transfer on multi-layers skin. A typical heat treatment method (heating by laser at skin surface) is studied. The transient temperature field of skin is obtained. Effect of the several parameters on the temperature distribution is investigated. The relationship between blood perfusion rate and the temperature at skin surface in steady-state is fitted as a formula. The results of the article will be useful for accurate prediction of temperature in heat therapy. In addition the formula about blood perfusion rate and the temperature at skin surface in steady-state can be used for nondestructive test of blood perfusion rate.
