Numerical Study of Non-Linear Three-Phase-Lag Model for Heat Transfer in Tissue During Thermal Therapy

In this article, the simulation based mathematical modelling on bioheat transfer in living tissue is studied by using non-linear three-phase-lag bioheat transfer model (TPLBHT). The TPLBHT model includes phase lag time due to heat flux, temperature gradient and temperature displacement with energy balance equation. A hybrid numerical method is used for solution which is based on Finite-Difference method with central difference method and Runge-Kutta (4, 5) method to find the solution. The effect of dimensionless temperature with dimensionless time for different parameters like blood perfusion coefficient, metabolic heat source coefficient, phase-lag time parameters and parameters of TPL model are discussed. The full article is studied and presented in the dimensionless form.
