Effect of External Step Heating in Biological Tissue Using Dual Phase Lag Bioheat Transfer Model : a Numerical Approach

EasyChair Preprint no. 7333

Abstract

This paper explains the thermal behavior of bio-logical tissues exposed to step heating using the DualPhase Lag (DPL) bioheat transfer model. This investigation is focused on the effect of thermal-lag times associated with the thermal inertia and microstructural interaction as well as the impact of other thermo-physical parameters such as core body temperature and blood perfusion rate. A Backward Time, Cantered Space (BTCS) implicit scheme is employed for discretization through finite difference method (FDM). Finally, a comparison is proposed be-tween Penne's model, the Thermal wave model, and the DPL model to illustrate the effect of different relaxation times.

Keyphrases: BTCS discretization scheme, Dual-Phase Lag model, finite difference method, Penne's bioheat model, Thermal Wave model
