FDM analysis for squeezed flow of hybrid nanofluid in presence of Cattaneo-Christov (C-C) heat flux and convective boundary condition

Abstract

In this paper we have computed squeezing channel flow of hybrid nanofluid (Al2O3+SiO2+ Water). The lower surface of the channel is subjected to stretching property. Upper surface moves (squeezes) towards lower surface. Heat transport is explored through Cattaneo-Christov (C-C) heat flux and convective boundary condition. This model is constructed via modification in Fourier’s law by addition of thermal relaxation time factor. The governing expressions (PDEs) are non-dimensionalized through suitable variables. The obtained non-dimensional systems (PDEs) are solved using FDM (finite difference method). Velocities, temperature and skin friction are graphically evaluated with respect to influential variables.
