Numerical Solution of Subdiffusion Bioheat equation with Single Phase lag

Received Date:23 December 2023, Accepted Date:12 February 2024, Published Date:28 February 2024


Objectives: The aim of this study is to investigate thermal beheviour of living tissues, for this we use subdiffusion bioheat equation with single phase lag model. Methods: The Crank-Nicolson finite difference scheme is used for subdiffusion bioheat equation with single phase lag by using Caputo fractional derivative. A Python program is used to calculate a numerical solution, which is then visually depicted through graphical representation. Finding: We discuss significance of heat flux time relaxation parameter and fractional parameter. To explore our findings, we conducted comparative analysis of subdiffusion bioheat equation with single phase lag model with classical bioheat model and fractional bioheat model. Moreover, We discussed stability and convergence of developed scheme. Novelty: The bio heat equation can be effectively addressed using the Crank-Nicolson finite difference method of fractional-order. Developed Python program provides effective tool for getting numerical solution of fractional differential equation. Single phase lag model is useful for short time heating process.
