Thermal and hydrodynamic analysis of a conducting nanofluid flow through a sinusoidal wavy channel

Abstract

The main objective of current study is investigation on thermo-hydraulic behavior of nanofluids in a sinusoidal wavy channel as a novel geometry under influences of thermophoresis and Brownian motion. Differential quadrature method and optimal homotopy asymptotic scheme have been employed to solve the momentum, continuity, energy and nanoparticle fraction equations. The validity of the proposed approaches is evaluated by comparing with previously published results. The impacts of some other physical parameters on temperature, nanoparticle concentration and velocity profiles will be analyzed in details. For instance, the results indicate that increment of the thermophoresis leads to enhance in values of temperature distribution. Also, the volume fraction of nanoparticle enhances by decreasing the parameter of thermophoresis.
