Abstract
In the presence of magnetic field, steady flow of a micropolar fluid due to a stretching cylinder is studied. Viscosity and thermal conductivity are assumed to be inverse linear functions of temperature. The governing partial differential equations are converted into ordinary differential equations using suitable similarity transformations and then solved by fourth order Runge-Kutta shooting method and developing Matlab programme. The graphs show the effects of different parameters and the skin friction coefficient and Nusselt numbers are shown in tabular form.
Highlights
From the very beginning of the introduction of micropolar fluid theory by Eringen (1964, 1966, 1972), it becomes an attractive part of so many researchers
We have extended the work of Nazir and Shafique (2015) and analyse the effects of variable viscosity and thermal conductivity on micropolar fluid flow due to a stretching cylinder in the presence of magnetic field
It is observed that velocity increase for the increase of micropolar parameters C1 and C2, viscosity parameter θr and thermal conductivity parameter θc
Summary
From the very beginning of the introduction of micropolar fluid theory by Eringen (1964, 1966, 1972), it becomes an attractive part of so many researchers. Sheri and Shamshuddin (2015) studied heat and mass transfer on the MHD (magnetohydrodynamic) flow of micropolar fluid in the presence of viscous dissipation and chemical reaction. MHD flow and heat transfer of a micropolar fluid over a stretching surface with heat generation (absorption) and slip velocity was studied by Mahmoud and Waheed (2012).
