Numerical modelling of bioheat transfer in multi-layer skin tissue domain subjected to a flash fire

摘要

In the paper the numerical analysis of thermal processes proceeding in the multi-layer domain of skin tissue subjected to an external heat source is presented. Heat transfer in the skin tissue was assumed to be transient and two-dimensional. The bioheat transfer in the domain considered is described by the system of the Pennes equations. On the assumed part of skin surface the Neumann condition determining the value of external heat flux is given, on the conventionally assumed internal surfaces of the tissue the no-flux condition is accepted. For time t = 0 the initial distribution of temperature is known. The main subject of the paper is the sensitivity analysis of temperature field with respect to the skin tissue parameters. On the stage of numerical computations the boundary element method has been used. In the final part of the paper the examples of results obtained are shown.
