Abstract
This research inspects the liquid film flow of the nanofluid in a permeable medium with the consequence of thermal radiation over a stretching sheet. The viscidness and thermal conduction of the nanofluid varies with temperature in such a manner that the thermal conductivity considered in direct relation while the viscosity considered inversely proportional to the temperature field. The invariable magnetic field applies vertically to the flow field in the existence of entropy generation. For the above-mentioned nanofluid study, Buongiorno’s model is used. The leading equations are changed into a set of third- and second-order nonlinear coupled differential equations. These nonlinear ordinary differential equations are solved using the optimal approach of homotopy analysis method. The physical appearance of the modelled parameters based on the liquid film thickness is mainly focused. Furthermore, the influence of embedded parameters like variable viscosity parameter [Formula: see text] Prandtl number [Formula: see text] Schmidt number [Formula: see text] Brinkman number [Formula: see text] Brownian motion constraint [Formula: see text] thermophoresis constraint [Formula: see text] magnetic parameter [Formula: see text] thermal radiation parameter [Formula: see text] Reynolds number [Formula: see text] diffusion coefficient [Formula: see text] non-dimension temperature variation [Formula: see text] and non-dimension concentration variation [Formula: see text] is observed on the velocity pitch, temperature gradient and concentration sketch. The consequence of parameters due to entropy generation and Bejan number has also been observed in this work. The important physically quantities of skin friction coefficient, the local Nusselt number and Sherwood number have also been studied. Residual error and optimal values have been calculated for the range of each physical parameter. The present work is compared with the published work and the comparison has been shown physically and numerically.
Highlights
Liquid film flow is the significant natural phenomena
The practical application related to the investigation of thin film flow is an inspiring relationship between fluid mechanics and fluid dynamic
According to the above important discussion, the aim of the present work is to extend the idea of Qasim et al.[14] for further study by including the entropy generation terminology in the nanofilm flow and using the clue of varying viscosity and varying thermal conductivity terms
Summary
Liquid film flow is the significant natural phenomena. The raised extensive interest and its huge applications in the area of industries, engineering and technology in a last few years clarify its importance in nature. The similar research was further extended by Usha and Sridharan.[8] The heat transfer consequence of the liquid film investigation on the parallel sheet was considered by Liu and Andersson.[9] To solve the problem using numerical methods and deliberate the limited flow constraints. Liu[28] studied flow and heat transmission of an electric conducted fluid of second grade in a permeable surface on an extending sheet having a transverse magnetic field.
