Heat Transfer in Biological Tissues
M.E. Bravo, P. De Jesús Sánchez, R.O. Vargas Aguilar and A.E. Chávez
Abstract
The heat transfer process in biological tissues is studied through the
Pennes bioheat equation, in dimensionless form, taking into account the temper-
ature gradient delay by the Maxwell-Cattaneo model. Stochastic perturbations from
the environment applied on the surface of the tissue and different external energy
sources are considered. Comparison of temperature distributions with constant bio-
logical parameters are presented, from the skin surface and through the tissue transfer
processes and to contribute to a better understanding on how nature works, it is essen-
tial to include biological, physical and biochemical.
1 Introduction
The complexity of themass, energy and amount of motion transfer processes that take
place in biological tissues has drawn the attention to the need for multidisciplinary
research, in which fundamental concepts of engineering and physics are integrated
with biological sciences. In order to develop mathematical models that adequately
represent biological factors into the actual phenomenological models that describe
different transfer processes found in living tissues. In addition, the analysis of the
transport mechanisms will serve to innovate and optimize diagnostic and therapeutic
