文摘
Micropolar fluid behavior on steady MHD free convection and mass transfer through a porous medium with constant heat and mass fluxes has been studied numerically. Nachtsheim-Swigert iteration technique is used as the main tool for the numerical approach. This study is mainly based on the similarity approach. Similarity equations of the corresponding momentum, angular momentum, temperature and concentration equations are derived by employing the usual similarity technique. The dimensionless similarity equations for momentum, angular momentum, temperature and concentration equations are solved numerically by above mentioned iteration technique. With the help of graphs, the effects of the various important parameters entering into the problem on velocity, microrotation, temperature and concentration field within the boundary layer are separately discussed. Finally the effects of the pertinent parameters on the skin friction coefficient at the plate are discussed with the tables.
