Abstract

Impact of Space-Dependent Thermal Conductivity on Heat Transfer in a Vertical Annulus with Asymmetric Surface Heating

Highlights

  • IntroductionOver the past two centuries, thermal conductivity (often denoted k, λ, or κ) is the property of a material to conduct heat

  • Over the past two centuries, thermal conductivity is the property of a material to conduct heat

  • The solutions obtained are seen to be govern by Prandtl number (Pr), thermal conductivity variation parameter (B), suction/injection parameter (S), radius ratio (λ) and cylinder surface temperature difference ratio

Summary

Introduction

Over the past two centuries, thermal conductivity (often denoted k, λ, or κ) is the property of a material to conduct heat. Prasad et al [1] studied the effects of variable fluid properties on the hydromagnetic flow and heat transfer over a non-linearly stretching sheet. Animasaun [2] investigated the effect of thermophoresis, variable viscosity and thermal conductivity on free convective heat and mass transfer of non-darcian MHD dissipative casson fluid flow with suction and order of chemical reaction. He concluded that viscosity parameter as well as thermal conductivity parameter decreases fluid temperature. Other works on temperature dependent thermal conductivity can be found in [3,4,5,6]
