Thermally fully developed CNTs suspended nano fluid flow through annular sector duct

Abstract

Here we simulate hydrodynamically and thermally fully developed carbon nano tubes, ( CNTs) suspended nano fluid flow through annular sector duct. Hydrodynamic results are found by using no slip boundary condition on the solid walls of duct; whereas H1 and T thermally fully developed conditions are accounted to evaluate the thermal results. CNTs are considered to be single wall, ( SW)/multi walls, ( MW). Power-law discretized scheme is used to transform the non-linear cross sectional convection-diffusion terms in algebraic form by using the control volume based method. With the help semi-implicit method for pressure-linked equations-revised, ( SIMPLER), a system of discretized algebraic equations is solved. Forced convective flow is carried out for different annular configuration parameters and contribution of CNTs in base fluid (i.e. pure water) at Pr = 6.2. Limiting case friction factor and heat transfer results show good agreement with already published data.
