Effects of Temperature Fluctuations on Darcy-Forchheimer Flow of Oil-Based Nanofluid with Activation Energy and Velocity Slip

Abstract

The effects of fluctuating temperature on Darcy-Forchheimer flow of oil-based nanofluid with activation energy and velocity slip has been analyzed. Similarity transformation was used to transform the governing partial differential equations into coupled nonlinear ordinary differential equations and solved numerically with the aid of the fourth order Runge-Kutta algorithm with a shooting technique. Results for the embedded parameters controlling the flow dynamics have been tabulated and illustrated graphically. The slip velocity parameter was found to enhance the Nusselt number but depleted both the skin friction coefficient and Sherwood number while the local inertial was noted to increase both the skin friction coefficient and Sherwood number but diminishes the Nusselt number. These results indicate that the velocity slip parameter and local inertial coefficient can be used to control flow characteristics in industrial and engineering systems.

Cattaneo-Christov Heat Flux Model Effect on Magnetized Maxwell Nanofluid Flow over a Stretching Surface

“…Because it offers a more accurate picture of how flow behaves in porous media, the Darcy-Forchheimer model has seen extensive usage in the research of magnetohydrodynamics Maxwell flow over a stretching sheet [5]. Because it takes into account both viscous and inertial forces in porous media, the Darcy-Forchheimer model is an excellent choice for analysing the behaviour of fluids in circumstances in which both forces play a substantial role, such as MHD Maxwell flow over a stretching sheet [6,7]. Studies have demonstrated that the Darcy-Forchheimer model provides a better understanding of the flow behaviour in porous media compared to the standard Darcian model.…”
