Investigation of quadratically stratified squeezed Casson fluid flow with slip features over a convectively heated surface

Abstract

There are diverse engineering and industrial related dynamical systems where the dissipative phenomenon in non-Newtonian fluids have given great significance. Example includes aerodynamics heating process, flows of polymer processing (injection molding, extrusion, etc.), and flow of fluid in small devices under associated heat transport process. Here, this attempt presents an analytical study of the squeezing mechanism. The squeezed material is presented utilizing the Casson incompressible fluid model. Viscous dissipation impacts along with convective surface conditions are retained in this study. A slip and stratification analysis in respect of unsteady flow, heat and mass transfer is performed in this attempt. The governing equations under the squeezing process are made first simplified and then transformed into dimensionless form using the similarity variables. Here, homotopic technique has been implemented in order to solve the dimensionless equations. Outcomes of velocity, heat, and mass transport mechanisms are discussed graphically in detail against pertinent parameters. In this analysis the heat and mass transport increases with increasing thermal and solutal Biot number, however the velocity decrements near the sheets as the slip parameter increases. Moreover, study concludes that squeezing mechanism intensifies the flow velocity. Phenomenon of squeezing experiences numerous industrial related processes such as mechanisms of lubrication, engine cooling system, designing permeable surfaces to minimize drag, etc., Force of drag is decreased further because of squeezing parameter. Therefore, because of low drag force, minimum amount of energy related resources can be utilized.
