Opis:: An analytical Study of double diffusive MHD flow of a chemically reacting alumina nanofluid past an infinite flat plate is made. Laplace transform method is employed to determine the solution of the governing equation and its analysis showed that increase in both Reynolds number and Prandtl number bring about an increase in the rate of heat transfer coefficient. Skin friction is shown to reduce as the Reynolds number increases. Increase in Reynolds number and Schmidt number, increases the mass transfer coefficient of alumina nanofluid. Generally, comparison is made with other work and an appreciable trend is observed.

Opis:: The stability of micropolar fluid flow in a channel under the influence of heat function, magnetic field and radiation was investigated. Using the similarity solution and non-dimensionalizing, the governing partial differential equations (PDEs) where transformed to a set of non-linear differential equations (ODEs). We therefore perturbed the system and determined the stability of the system. Wolfram 9 software (Mathematica) was used to analyze the various stability effect of the material parameters on the fluid flow. The graphical results reflects the expected physical behavior of the flow configuration under consideration. The study reveals that the Prandtl (Pr), wave (a), Radiation (R) and heat function parameters at a certain critical value of the wave number hastens the onset of stability. While the Electroconductivity (σ), Magnetic field (M), Micropolar (K) and Microrotational (λ) parameters delays the onset of stability. The result are in agreement with the works of other literature sited.
