Numerical study of heat and mass transfer for micropolar fluid flow due to two symmetrical stretchable disks

Abstract

Abstract In this study, heat transfer is analyzed for an incompressible steady laminar micropolar fluid flow among two symmetrical stretchable disks. The associated partial differential equations (PDEs) are converted into ordinary differential equations (ODEs) through appropriate similarity transformations and then solved numerically by applying the quasi-linearization method along with the finite difference method (FDM). This impact from certain inclusive parameters in the heat transfer and fluid flow is presented schematically. The results are tabulated and depict that the shear stress rises for the upper disk and the opposite trend for the lower disk. It is also noted that a couple stress and heat transfer rates were reduced across the disks. The slip factor enhances the tangential stress on the top disc and it reduces on the bottom disc. Twisting stress decreases where ϕ ′ η increases due to the effect of the slip factors.
