Abstract

This paper analyses the mixed convection flow of an incompressible micropolar fluid along a semi-inŞnite vertical plate with uniform heat and mass flux in the presence of transverse magnetic Şeld. The governing nonlinear partial differential equations are transformed into a system of coupled nonlinear ordinary differential equations using local similarity transformations and then solved numerically using the Keller-box method. The non-dimensional velocity components, microrotation, temperature and concentration are presented graphically for various values of magnetic parameter, Hall parameter, Ion-slip parameter, Dufour and Soret numbers. In addition, the Nusselt number, the Sherwood number, the skin-friction coefficient, the wall couple stress are shown in a tabular form

Keywords
