Thermal Analysis of Casson Hybrid Nanofluid Flow With Solar Radiation and Inclined Magnetic Field

ABSTRACT The enhanced thermal conductivity and tunable flow behavior of nanofluids contribute to improved heat absorption, transport efficiency, and temperature regulation in advanced engineering systems. Considering these important applications, the present work investigates the influence of solar thermal radiation on the flow of a magnetized Casson hybrid nanofluid on a variable porous stretching sheet. The fluid rotates about the z ‑axis, with magnetic field effects applied in inclined direction to the flow. The analysis incorporates various flow conditions, including Joule heating, nonlinear convection, and viscous dissipation. The governing equations are reduced to dimensionless form and solved numerically using the bvp4c method. As outcomes of this study, it has deduced that an intensification in the linear and nonlinear Grashof numbers, as well as the variable porous factor, leads to an enhancement in primary velocity while simultaneously causing a decline in secondary velocity.
