Analysis of sodium chloride and sucrose diffusions in mixed convective nanoliquid flow

Abstract

Combined convection nanoliquid flow involving three diffusive components is investigated along with a moving plate and magnetic field effects. A wall heating/cooling analysis is carried out, given its engineering and industrial applications. The conservation equations governing the flow are solved by utilising a Quasilinearization technique and finite difference method. Heat, Sucrose and Sodium Chloride are taken as the three diffusive components. The numerical simulation results show that the rise in the value of the thermophoresis parameters Nt accelerates both the temperature profile and the nanoparticle Sherwood number. The temperature profile increases, while the nanoparticle Sherwood number reduces for greater values of Nb, which represents the Brownian diffusion. The rate of transfer of heat and the friction at the surface diminishes for higher values of the magnetic and nanoparticle buoyancy ratio parameters. The heat flux at the plate reduces in-wall cooling case and increases in-wall heating case, for rising values of thermophoresis parameter Nt, whereas, for rising values of Brownian diffusion parameter Nb, the heat flux reduces considerably in both the cases.
