Summary: This article investigates the MHD Jeffrey fluid flow over a stretching cylinder with convection. The Cattaneo-Christov heat flux model is used instead of the Fourier law of heat conduction to derive an energy equation. The mathematical model leads to a system of nonlinear PDEs in cylindrical coordinates, which are transformed into ordinary differential equations using similarity transformations. The numerical solutions are obtained using shooting and BVP4C methods, and the results are validated. The effects of different parameters on velocity, temperature, and concentration are analyzed through graphs, and the skin-friction coefficient, local Nusselt and Schmidt numbers are discussed and tabulated. The novelty of this work lies in the study of Cattaneo-Christov MHD heat flux for Jeffrey fluid flow with convective conditions.

Summary: This research numerically investigates the magnetohydrodynamics boundary layer flow of a Casson fluid in a rotating frame through a porous medium caused by an exponentially stretching surface. The study incorporates the phenomenon of relaxation time for thermal waves with chemical reaction effects to explore the transport properties of thermal and solutal energy. The influence of bio-convection and stratification on energy transport is also considered. The numerical results show that the resistance to fluid motion increases with the magnitude of the Casson parameter, leading to a reduction in the flow field. Higher values of thermal relaxation time slow down the propagation of heat waves.

Summary: The combined impacts of bio-convection and magnetic field on boundary layer magnetohydrodynamic unsteady Sakiadis and Blasius flow of nanofluid with accretion/ablation of the leading-edge are investigated. The study reveals that the growing strength of the magnetic field reduces the velocity of the boundary layers in both the Sakiadis and Blasius flows. It is also observed that the concentration profile directly decreases in response to the Lewis number, bioconvective Peclet number, and the chemical reaction. The temperature of the fluid rises proportionally with the increasing values of each of the radiative parameter (Rd), Biot number (Bi), and thermophoretic parameter (Nt).

Summary: This study aims to analyze the heat transfer behavior of the MHD micropolar dusty hybrid nanofluid in the presence of a heat source/sink and linear thermal radiation over a three-dimensional surface. A novel implementation of an intelligent numerical computing solver based on MLP feed-forward backpropagation ANN with the Levenberg-Marquardt algorithm is provided in the current study. Dusty hybrid nanofluid has a greater influence than dusty fluid, and improving the values of the vortex viscosity and fluid-particle interaction parameters increases the rate of heat transfer. The temperature profile of dusty and dusty hybrid nanofluid rises for higher values of the thermal radiation parameter.
