Influence of differently shaped copper nanoparticles in mixed convection flow through a curved wavy channel

Abstract

This article analyses the effects of differently shaped copper nanoparticles on mixed convection peristaltic transport of water-based nanofluid via a curved channel. Momentum and energy equations are derived and simplified under long wavelength and physically small Reynolds number assumptions. Experimentally tested correlations related to thermophysical properties of nanofluids are incorporated into these equations to examine the effects of nanoparticles. Obtained equations are further transformed into dimensionless forms by utilizing dimensionless variables. Numerical solutions are computed using software Mathematica. Effects of physical parameters on trapping phenomena, pressure gradient, velocity and temperature fields are examined. It is observed that the magnitude of the axial pressure gradient and heat transfer rate is maximum for nanofluid suspended with platelet shaped nanoparticles.
