Thermal propagation analysis for living tissue with surface heating

This work theoretically investigates the thermal behavior in a living tissue subjected to constant, sinusoidal, or step surface heatings with the thermal wave model of bioheat transfer. The attention is paid on the cases that heat mainly propagates in the direction perpendicular to the skin surface. The effects of thermal physical properties on the wave like behavior of bioheat transfer are investigated. A modified discretization scheme based on the Laplace transform is proposed to solve the present problem. The comparison between the present numerical results and those in the literature is made to evidence the present results rational and reliable.
