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 : Mixed convection, Micropolar ﬂuid, Hall and ion slip, Soret and Dufour, Heat and mass transfer
