Abstract

ABSTRACT: The utilisation of nano-fluids is of pronounced importance in industries. GO-MoS2 nanocomposite exhibits significant photocatalyst performance and is applied in water remediation and energy storage. In this problem, we have analysed a three-dimensional G O − M o S 2 / Casson hybrid nanofluid flow between two parallel plates in the magnetic field, nonlinear thermal radiation, heat absorption and viscous dissipation. A suitable similarity transformation is used and then solved using MATLAB bvp4c routine with the shooting techniques. Casson and magnetic parameters enhanced the skin friction while the reverse trend for slip parameters. The Biot number decelerates the heat transfer rate at the surface, while the heat generation enhances the heat transfer rate. Entropy generation nonlinearly boosts up with an increase in the magnetic field and the Brinkman number, while an opposite phenomenon is observed for the Bejan number. Heat transfer, entropy generation and the Bejan number observed higher values for the hybrid nanofluid than for the general nanofluid.
