Abstract

The problem of mixed convection in a nanofluid along an inclined wavy surface embedded in a non-Darcy porous medium with radiation effect is analyzed. Coordinate transformation is employed to transform the complex wavy surface to a smooth surface. The governing equations are transformed into a set of ordinary differential equations using the appropriate similarity transformation and then solved using the successive linearization method. The present results are compared with previously published work and are found to be in very good agreement. The effect of pertinent parameters on the nondimensional velocity, temperature, nanoparticle volume fraction, heat, and nanoparticle mass transfer rates is studied and presented graphically.

Highlights

The research on heat transfer in nanofluids is receiving much attention from the past several years due to its unique characteristics in thermal engineering fields and broad range of applications such as microelectronics, microfluidics, solidstate lighting, transportation, biomedical, and manufacturing
Choi et al [2] showed that the addition of a small amount of nanoparticles to conventional heat transfer liquids increased the thermal conductivity of the fluid
A detailed review of the literature on nanofluids and applications of nanofluids can be found in the book by Das et al [3] and collection of papers by Kakacand Pramuanjaroenkij [4] and Puliti et al [5]. These reviews discuss in detail the work done on convective transport in nanofluids

Summary

Introduction

The research on heat transfer in nanofluids is receiving much attention from the past several years due to its unique characteristics in thermal engineering fields and broad range of applications such as microelectronics, microfluidics, solidstate lighting, transportation, biomedical, and manufacturing. Choi et al [2] showed that the addition of a small amount (less than 1% by volume) of nanoparticles to conventional heat transfer liquids increased the thermal conductivity of the fluid. A detailed review of the literature on nanofluids and applications of nanofluids can be found in the book by Das et al [3] and collection of papers by Kakacand Pramuanjaroenkij [4] and Puliti et al [5]. These reviews discuss in detail the work done on convective transport in nanofluids
