Spectral Numerical Study of Entropy Generation in Magneto-Convective Viscoelastic Biofluid Flow Through Poro-Elastic Media With Thermal Radiation and Buoyancy Effects

Abstract Electromagnetic high-temperature therapy is popular in medical engineering treatments for various diseases including tissue damage ablation repair, hyperthermia, and oncological illness diagnosis. The simulation of transport phenomena such applications requires multi-physical models featuring magnetohydrodynamics, biorheology, heat transfer, deformable porous media. Motivated by investigating the fluid dynamics thermodynamic optimization processes, present article, a mathematical model developed to study combined influence thermal buoyancy, magnetic field radiation on entropy generation, momentum transfer characteristics electrically conducting viscoelastic biofluid flow through vertical medium. It assumed that generated within both viscous Darcy (porous matrix) dissipations. governing equations velocity, solid displacement, temperature are formulated. boundary value problem normalized with appropriate transformations. nondimensional conditions solved computationally using spectral method. Verification accuracy conducted via monitoring residuals solutions. effects parameters temperature, generation depicted graphically discussed. Increasing drag found reduce production. Entropy production enhanced an increase buoyancy parameter volume fraction fluid. novelty work simultaneous inclusion multiple thermophysical phenomena, consideration coupled thermal/fluid/elastic computations provide insight into multiphysical electromagnetic radiative good benchmark more advanced simulations.
