Abstract

In the study, the steady, laminar, incompressible, convective flow of a viscous fluid over a moving plate is investigated theoretically by adopting different types of nanoparticles. Radiation, internal heat generation and viscous dissipation effects are considered in the energy modeled equation. The governing flow equations for the momentum and temperature are reduced to dimensionless form via similarity transformations. The solutions to the resultant equations alongside with the transformed boundary conditions are numerically obtained using MATLAB package bvp4c. Validation with earlier studies are done for the non-internal heat generation case for two distinct nanoparticles of type Cu-water and Al-water. Extensive visualization of flow rate and heat distributions for various emerging parameters are examined. Temperature is consistently enhanced with a rising Eckert number of both types of nanofluids, whereas it is strongly reduced with rising values of radiation term. Heat transfer coefficient is consistently increased with a nanoparticle volume fraction of high convective heat in the medium.

Highlights

In polymer fabrication at high temperature [1, 2], radiative heat distribution takes place in addition to heat convection and heat conduction
In the presence of other effects such as magnetohydro-dynamics, rheology are the effortless pragmatic approach that frequently features an approximation algebraic flux that can be of the Traugott P1 flux model, Milne-Eddington type, Rosseland type, six flux Hamaker formulation, Schuster-Schwartzchild type etc
Where (′) represents derivative with respect to, is the slip velocity term, the term Nr denotes thermal radiation, Ec represents Eckert number, Pr stands for Prandtl number, and S is the local injection parameter (< 0), or the local suction parameter (> 0) or these terms are respectively denoted as follows physics validity and the results offered in this study are locally self-sufficient as seen in Sparrow and Yu [29]

Summary

Introduction

In polymer fabrication at high temperature [1, 2], radiative heat distribution takes place in addition to heat convection and heat conduction. In coating flows of multi-physical, high radiation optical thicknesses are practically and correctly presented using the Rosseland model. Though it does not permit the stimulation of spectal effects or optical viscosity, but provides an evaluating mechanism for the relative role of heat flux radiation and heat conduction. Numerous scholars have investigated radiative heat transfer in materials processing including Shamshuddin et al [3] (bio convection nanofluid), Kadir et al [4] (thermal stress analysis), Liu et al [5] (multi laser processing) and Yue and Reitz [6] (internal combustion energies)
