Abstract

This work deals with a novel numerical technique for similarity analysis of the effect of magnetic field on free convection in micropolar fluid about a vertical strip in the existence of mixed thermal boundary conditions and non-uniform wall concentration boundary conditions. The governing boundary layer equations of the physics of the present problem are cast into coupled nonlinear ordinary differential equations using the Lie Group point transformations. These resulted equations engaging in m which speculates the values zero,one and infinity leads to the prescriptive temperature case, prescriptive heat flux case and radiation boundary conditions case at wall, has been solved using the novel numerical technique, paired quasi-linearisation method (PQLM). The results obtained are corroborated and are establish to be matched with earlier works.
