Abstract
This article looks at the steady flow of Micropolar fluid over a stretching surface with heat transfer in the presence of Newtonian heating. The relevant partial differential equations have been reduced to ordinary differential equations. The reduced ordinary differential equation system has been numerically solved by Runge-Kutta-Fehlberg fourth-fifth order method. Influence of different involved parameters on dimensionless velocity, microrotation and temperature is examined. An excellent agreement is found between the present and previous limiting results.
Highlights
Understanding the flow of non-Newtonian fluids is a problem of great interest of researchers and practical importance
The micromotion of fluid elements, spin inertia and the effects of the couple stresses are very important in micropolar fluids [1,2]
The fluid motion of the micropolar fluid is characterized by the concentration laws of mass, momentum and constitutive relationships describing the effect of couple stress, spin-inertia and micromotion
Summary
Understanding the flow of non-Newtonian fluids is a problem of great interest of researchers and practical importance. During the past few decades, several researchers have concentrated on the boundary layer flows over a continuously stretching surface This is because of their in several processes including thermal and moisture treatments of materials in metallurgy, in the manufacture of glass sheets, in textile industries in polymer processing of chemical engineering plants. The boundary layer flow of a viscous fluid over a stretching sheet was initially studied by Crane [10], followed by many investigators for the effect of heat transfer, rotation, MHD, suction/injection, non-Newtonian fluids, chemical reaction etc. Salleh et al [24] numerically investigated the boundary layer flow of viscous fluid over a stretched surface in the regime of Newtonian heating. Basic Equations We consider the steady boundary layer flow of an incompressible Micropolar fluid induced by a stretching surface. The governing equations of the boundary layer flow in the present study are
