Non-linear thermal radiation impacts on MHD nanofluid flow in a rotating channel with Darcy-forccheimer model: An entropy analysis

Abstract

The current work explores the fluid and heat transfer properties of three-dimensional steady flow of electrically conducting hybrid nanofluid between two rotating parallel plates saturated in a porous medium with Darcy-Forchheimer model. Two nanoparticles, Silver ( A g ) and multi wall carbon nanotube ( M W C N T ) have been taken with base fluid water. Further, it also reflects the collective effects of magnetic field, viscous dissipation, heat source, buoyancy force, and nonlinear heat radiation on entropy production rate. The transformed equations are numerically computed for normal, axial, and transverse velocities and temperature distributions using the bvp4c technique. Graphs and tables are used to visualize and analyze the significant results of prominent parameters on fluid distributions. The amalgamation of Ag + MWCNT\H 2 O exhibits improved and embellished thermal properties. The findings exhibits that the magnetic parameter declines the velocity and improves the temperature. The radiation parameter declines the temperature field while heat source parameter upsurges it. Further, the suction/injection parameter enhances the fluid velocity. An entropy generation rate is increased by Eckert number and radiation parameter. This study's findings have implications for various engineering and industrial processes in the development of efficient thermal energy systems that employ nanofluids and hybrid nanofluids for heating and cooling purposes. This study is validated by prior research.
