Thermal drift and force convection analysis of nanofluid due to partially heated triangular fins in a porous circular enclosure

Abstract

Abstract The main emphasis of this article is to analyze the simultaneous effects of thermal drift and force convection on water based single wall carbon nanotubes (SWCNTs) in a porous circular duct. Equilateral triangular fins which are enclosed in a circular cavity having vertical and horizontal side of triangular fins are moving. Internal heat generation/absorption is considered to determine the thermal drift. Impact of inclined Magnetohydrodynamics (MHD) has been introduced. The governed equations are solved through weighted residue method of Finite Element Method (FEM). Effect of various parameters, that is: Reynolds number, nanoparticles, porous medium and absorption/generation on flow patterns and heat transfer were worked out. The heat transfer rate at different heated fins has been investigated for various parameters. This study carries out significant impact of Q on temperature profile and Local Nusselt. Local Nusselt number against heated walls decreases with increase of porosity parameter and increases in case of heat generation. Streamlines decreases with increase of quantity of solid volume fraction in enclosure. Significant effect of Re observed in transformation of heat in circular duct.
