【 摘 要 】

The present study investigates the effects of Soret and Dufour on MHD non-Darcy convective flow of a viscous incompressible radiating micropolar fluid past an inclined permeable plate with non-uniform heat source or sink and chemical reaction. The flow field with partial differential equations are converted to a system of nonlinear coupled ordinary differential equations by similarity transformations and solved employing shooting method. Swiftness in the momentum of the fluid is observed as the Darcian and fluid parameter ascends. Speed of the fluid in angular rotation ascends as the material parameter or sheet inclination or magnetic parameter increases. Molecular diffusion rate is more as the microparticles undergo chemical reactions. While the thermal distribution rate reduces because of the reactions. Rest of the results are interpreted graphically. A good agreement is observed with the previous publications. The presence of chemical reaction makes the problem industrially applicable taking the case of heterogeneous reactions.
