Abstract

AbstractA numerical investigation into the effect of temperature-dependent fluid properties on the thin film flow along an inclined heated plate is presented. The equations governing the coupled flow and heat transfer are formulated based on couple stress non-Newtonian model. Solutions of the coupled nonlinear differential equations are tackled numerically by using the combination of shooting method and the Fehlberg-Runge-Kutta method. Findings are presented graphically and discussed precisely.

Highlights

The importance of thin uid ow along an inclined plate in many physical and engineering environment has accounted for the increasing number of studies in recent times
Motivated by several ndings of many thermal and mechanical engineering applications, the present article is devoted to temperature dependent properties of thin lm ow
In the context of thin lm ow, several works have been documented in the literature on thermal instability with or without temperaturedependent properties
