A Study on Bio-Thermal and Mechanical Interactions in Cylindrical Tissues with Experimental Data

Abstract

This work presents a method for numerically determining the thermal damages of cylindrical living tissue due to laser irradiation utilizing a hyperbolic bioheat model. To assess thermal injuries to the tissues, the Arrhenius relation must be used to assess the amount of denatured protein. Because the governing formulations are complicated, the finite element approach is used to solve this kind of problem. Moreover, the correctness of the numerical solution is confirmed by contrasting the numerical outcome of the finite element technique with recent experimental data. Explanatory graphics of the numerical results exhibit the increment in displacement, temperature, thermal damages and the stresses in responses to changes in the duration of laser exposure, the intensity of laser and blood perfusion rate. Additionally, the numerical outcome and the available experimental data are compared, showing that the present mathematical model is a useful tool for evaluating bio-heat transport in cylindrical human tissue.
