Effects of Thermal Radiation and Slip on Heat and Mass Transfer in MHD Nanofluid Flow With Cattaneo-Christov Heat Flux Over a Rotating Disk

Abstract

This work examines three-dimensional magnetohydrodynamic (MHD) nanofluid flow over a rotating disk, taking into account thermal radiation, thermophoresis, Brownian motion, and the Cattaneo-Christov heat flux model to account for cross-diffusion during heat transmission. Similarity transformations are used to convert the governing equations into nonlinear ODEs, which are then numerically solved using the fourth-order Runge-Kutta method and the bvp4c methodology. The graphical findings indicate how magnetic field, thermal slip, velocity slip, thermophoresis, and Brownian motion affect velocity, temperature, and concentration profiles. Thermal slip reduces velocity, increasing velocity slip results in less uniform temperature distribution, and the combination thermophoresis-Brownian effects have a major impact on thermal and concentration fields.
