APPROXIMATION OF TEMPERATURE DISTRIBUTION IN THE TISSUE OF THE HUMAN BODY BY FINITE DIFFERENCE METHOD

Abstract

Tissue is a group of cells with a similar structure that performs a function and biochemical processes are temperature dependent.
Hence, studying heat transfer plays a very important role in living systems. The temperature distribution in the tissue of the human
body is studied by developing a one-dimensional steady-state mathematical model in Cartesian coordinates based on Penne’s bio-heat transfer equation. Finite Difference Method solutions are found for one Dirichlet-type condition, one Neumann-type condition, and two mixed-type conditions at the boundary of the tissue in the human body. The values of Physical and Physiological parameters are taken from the literature. Results are drawn as graphs for Finite Difference Method solutions under four different boundary conditions using MATLAB 2015a. Also, results are compared with both the experimental data and analytic method solutions obtained by researchers.
