Abstract

Due to the "lengthy" thermal relaxation time in biological tissue, non-Fourier thermal behavior has been experimentally observed, attracting increasingly more attention to this phenomenon. The aim of this study is to develop a computational approach to examine the non-Fourier heat transfer process in skin tissue. The Dual-Phase-Lag (DPL) model is employed to study bioheat transfer in skin tissue for the first time, for it has the ability to characterize microstructural interactions in heat transport. Large discrepancies are found to exist amongst the predictions of Pennes model and Dual-Phase-Lag model of bioheat transfer.
