Impact of Chemical Reaction on Methanol-Silica-Titania Hybrid Nanofluid Filled Couette Channel

Abstract

Current paper focusses on the numerical simulation of two phase nanofluid flow in Couette channel containing novel SiO2-TiO2-CH3OH hybrid nanofluid (HNF). The hybrid nanoparticles silica(SiO2) and titania(TiO2) are added to base fluid methanol(CH3OH) in 1:1 ratio. The lower wall of channel is fixed, while the upper is set in uniform motion with convective cooling. The governed non-linear partial differential expressions(PDE) are answered employing finite difference method (FDM). A comparison of effect of hybrid nanofluid versus nanofluid (NF) is performed. The upshots of dimensionless quantities namely. nanoparticle volume fraction, magnetic field, chemical reaction parameter, Brownian motion and thermophoresis and Eckert number are reported graphically. The results demonstrate that SiO2-TiO2-CH3OH HNF shows significant impact over SiO2-CH3OH NF on velocity, temperature and concentration in the Couette channel.
