POROUS MEDIUM INFLUENCED DISSIPATIVE HYBRID CASSON NANOFLUID FLOW OVER A NONLINEARLY STRETCHING SHEET UNDER INCLINED OHMIC LORENTZ FORCE FIELD

The main aim of this numerical analysis is to demonstrate the influence of inclined magnetic field on the hybrid Casson nanofluid flow over a permeable stretching sheet with porous medium and thermal source/sink effects. A novel magnetic Ohmic heating and slip effects are introduced into the boundary conditions to simulate flow behavior accurately. Pertaining to this, the developed nonlinear coupled two-dimensional partial differential equations are rendered dimensionless through appropriate similarity transformations. The produced complex nonlinear boundary value nanofluid problem is solved by deploying a robust matlab-based Runge-Kutta fourth order scheme with shooting technique. The magneto-thermo nanofluid features are discussed through suitable graphical and tabular illustrations by virtue of velocity, temperature and concentration fields within the boundary layer regime. It is recorded from the current investigation that magnifying porous number and nanofluid volume fraction decelerates the velocity field. Enhancing radiation number amplifies the thermal transfer process. Accelerating Lewis number diminish the concentration field. Hybrid nanofluids show higher order thermal performance when compared to the usual nanofluids. Finally, the novelty of the present study is to generalize the former studies by including porous medium, Ohmic heating, heat source/sink, radiation, thermophoresis, and Brownian effects into the respective governing equations. A comparative study with the former results indicates good agreement with the previously published results. © 2024 by Begell House, Inc.
