Modeling and Simulation of the Dynamics of Fluid Flow and Heat Transfer for MRI-Guided Hyperthermia Treatment

Abstract

The current study modeled and simulated the dynamics of fluid flow and heat transfer for MRI-guided hyperthermia treatment. The blood flow along the artery was assumed to follow a Newtonian character. In the mathematical formulation, the flow was considered unsteady, laminar, incompressible, unidirectional, axisymmetric, and fully developed. Additionally, the effects of induced magnetic fields and Hall effects were deemed negligible. The study found that blood velocity and temperature significantly varied with the enhancement of magnetic strength, Reynolds number, Grashof number, and heat source parameter. In contrast, blood velocity showed a gradual variation with increasing Prandtl number and Eckert number. This study holds significant value for medical applications, offering a means to simulate various scenarios and providing a controlled, reproducible environment to test different parameters, optimize heating strategies, and predict patient-specific treatment responses. The model developed can be used to predict treatment outcomes, identify potential complications, and suggest optimized treatment protocols tailored to the anatomical and physiological characteristics of individual patients.
