Nonlinear analysis of thermo-magneto slip flow of Jeffery fluid in a wavy curved channel

Abstract

This study conducts an analytical examination of thermo-magneto-hydrodynamic slip flow of a Jeffery fluid through a porous wavy curved channel. The energy equation incorporates the effects of thermal radiation along with heat generation and absorption mechanisms. By formulating the governing equations in curvilinear coordinates and applying a regular perturbation method, closed-form expressions for the velocity, temperature, skin-friction coefficient, and Nusselt number are obtained. The parametric investigation indicates that both channel curvature and porous permeability enhance fluid transport, while the applied magnetic field suppresses motion. Thermal radiation notably intensifies heat transfer and facilitates bolus formation by decreasing the effective viscosity and augmenting buoyancy effects. Overall, the findings provide a useful theoretical basis for the design and optimization of advanced thermal management systems, polymer processing technologies, and MHD-based biomedical devices where non-Newtonian and radiative influences are significant.
