Magnetized Dracy-Forchheimer Casson nanofluid flow influenced by thermally radiative discharge concentration

Abstract This research is based on the examination of non-Newtonian fluids generated by the thermally radiative moving surface. The involvement of nanoparticles is modeled by using Buongiorno’s nanofluids model. The non-Newtonian nanofluids are highly useful in modern industrial developments like solar energy devices, heat exchangers, automobiles, lubricants, diesel engines, systems of thermal energy storage, solar collectors, nuclear reactors, and many others. The considered flow is laminar, incompressible, and two and three-dimensional. Casson fluid is considered a base fluid for the current research. In the momentum equation, porous medium and magnetic field impacts are incorporated. The energy and solutal species equations are considered, which are influenced by various physical effects like radiation, pollutant discharge concentration, CC – heat and mass flux, and chemical reaction. The boundary-layer assumptions are introduced for the development of a mathematical model. The feasible similarity constraints are developed to convert the dimensional mathematical model into dimensionless forms. Numerical computations through MATLAB’s bvp4c package were made for the solutions of the developed mathematical equations along with suitable boundary conditions. The results show that the velocity profile reduces due to improvement in the Casson and magnetic parameter, while the temperature profile shows improvement for the thermal radiation parameter. The concentration profile declines for the chemical reaction parameter, while an opposite trend is observed for the Biot number.
