Significance of skin vasodilation for bioheat transfer within transiently heated skin tissue

The current study presents a novel bioheat model for simulating heat transfer in skin tissue. The model, which is based on the Weinbaum-Jiji equation and incorporates the Cattaneo approach for flux in tissue, arteries, and veins, offers an improved representation of thermal dynamics in the skin compared to existing models. Numerical solutions of the model were obtained using the finite element method and were compared to experimental measurements. This study specifically highlights the incorporation of vascular inlet parameters and thermal relaxation effects in the thermal profile, which were not considered in previous models such as the Pennes model. This novel approach provides a more comprehensive understanding of heat transfer in skin tissue and has potential applications in fields such as thermal therapy and wound healing.
