  7. Abstract:
  8. Innovations in laser, microwaves, and similar technologies have significantly advanced thermal treatments for diseases or even injuries concerning skin tissue. For a thorough understanding in the underlying mechanisms of bioheat transfer behavior of skin,a1D unsteady non-dimensional hyperbolic model of heat transfer through this tissue with metabolic heat generation which is subject to specific boundary conditions, is solved numerically using the finite difference method. A thermal shock is generated at the base of the tissue, which moves forward with a finite speed. A Numerical solution for a simple one-layer skin tissue is obtained. Then, the effects of various parameters, time step, spatial coordinate step, metabolic heat generation and boundary conditions on temperature distribution are investigated.The temperature oscillations neighboring the thermal shock is totally unrealistic, therefore it indeed made the results unacceptable. the main focus of this study was on eliminating those inconsistencies by viscous dampers. In consequence, the general hyperbolic heat transfer equation is solved using the presented finite difference algorithm
