In this study، classical and generalized dual phase lag bioheat transfer models are applied for investigate thermal damage to skin tissue exposed to the transient heat flux. The analytical bioheat transfer analysis with transient heat flux on skin tissue has only been studied by Pennes and thermal wave models. This paper، for the first time، provides the analytical solution of the dual phase lag model in skin tissue under transient surface heating using Laplace transform method and inversion theorem. Since the dual phase lag model under certain circumstances reduces to the Pennes and thermal wave models، comparisons of the temperature responses and thermal damages between the these three models are carried out. The influence of porosity factor and coupling factor between blood and tissue on the thermal damage of tissue is investigated and the results demonstrate that increases in these factors respectively leads to the higher and lower tissue thermal damage and the effects of these factors on the thermal damage in the depth of tissue is lower than near the surface.
