Analysis of Hybrid Nanofluid MHD Flow and Heat Transfer Between Two Surfaces in a Rotating System in the Presence of Joule Heating and Thermal Radiation by Fibonacci Wavelet

Abstract

This study examines the magnetohydrodynamic (MHD) steady laminar incompressible viscous flow of a hybrid nanofluid (HNF) in a rotating system among two surfaces where the lower plate is stretchable, and the upper plate is permeable with the effect of thermal radiation and Joule heating by Fibonacci wavelet series collocation method (FWSCM). The governing nonlinear partial differential equations (PDEs) are transformed into coupled nonlinear ordinary differential equations (ODEs) using appropriate similarity transformations. These ODEs are solved by FWSCM. The accuracy of FWSCM is validated with the Haar wavelet collocation method (HWCM), Mathematica NDSolve command, and previously available numerical results. The effects of the suction/injection parameter, the volume fraction of the hybrid nanofluid, magnetic parameter, Prandtl number, Reynold’s number, radiation parameter, and rotation parameter on the flow velocities, heat transfer, and the physical quantities are examined through tables and graphs. It is found that the temperature profile exhibits the same behavior during the suction and injection process when the magnetic and rotation parameter increases.
