Second law analysis for couple stress fluid flow through a porous medium with constant heat flux

25 Sep 2019

In the present work, entropy generation in the flow and heat transfer of couple stress fluid through an infinite inclined channel embedded in a saturated porous medium is presented. Due to the channel geometry, the asymmetrical slip conditions are imposed on the channel walls. The upper wallofthechannelissubjectedtoaconstantheatfluxwhilethelowerwallisinsulated. Theequations governing the fluid flow are formulated, non-dimensionalized and solved by using the Adomian decomposition method. The Adomian series solutions for the velocity and temperature fields are thenusedtocomputetheentropygenerationrateandinherentheatirreversibilityintheflowdomain. The effects of various fluid parameters are presented graphically and discussed extensively.
