Thermodynamics analysis of Casson hybrid nanofluid flow over a porous Riga plate with slip effect

Abstract

The main objective of this work is to examine the nature of heat transfer and thermodynamics on Darcy-Forchheimer flow over porous Riga plate using Casson hybrid nanofluid. The impact of external forces i.e., slip velocity and magnetic field are discussed for pure fluid, nanofluid and hybrid nanofluid. The Hamilton-Crosser model of thermal conductivity is applied for the nanofluid as well as hybrid nanofluid. The existing nonlinear partial differential equations are solved by Runge-Kutta-Fehlberg (RKF) technique. The present code is validated numerically with previous works and found in good agreement with them. The results affirm that all fluids velocities declined with increase in Casson factor values. Moreover, increasing magnetization, the entropy profiles are depreciated significantly for the case of pure fluid, nanofluid and hybrid nanofluid. This comparative study reveals that hybrid nanofluid dominates on both nanofluid and pure fluid.
