Numerical investigation on the effect of tumor on the thermal behavior inside the skin tissue

Abstract

This paper investigates the thermal behavior inside skin tissue with the presence of a tumor by solving the Pennes bioheat equation. We apply the method of approximate particular solutions (MAPS) to simulate tumor in 3D. The MAPS is a kind of domain-type meshless collocation methods, which has the merits being free of mesh generation and numerical integration. To ensure the interface conditions were exactly satisfied, an affine space decomposition technique is adopted. After verifying the convergence of the proposed method, we provide various simulations to the thermal effects inside the skin tissue due to an arbitrary-shaped tumor, including the location, geometry and size.
