**Entropy generation in steady MHD flow due to a rotating porous disk in a nanofluid**

We consider the analysis of the second law of thermodynamics applied to an electrically conducting incompressible nanofluid fluid flowing over a porous rotating disk in the presence of an externally applied uniform vertical magnetic field. [1]

**Soret and Dufour effects on magnetohydrodynamic (MHD) flow of Casson fluid**

This article studies the Soret and Dufour effects on the magnetohydrodynamic (MHD) flow of the Casson fluid over a stretched surface. The relevant equations are first derived, and the series solution is constructed by the homotopic procedure. The results for velocities, temperature, and concentration fields are displayed and discussed. Numerical values of the skin friction coefficient, the Nusselt number, and the Sherwood number for different values of physical parameters are constructed and analyzed. [2]

**MHD flow of a Casson fluid over an exponentially shrinking sheet**

The magnetohydrodynamic (MHD) boundary layer flow of a Casson fluid over an exponentially permeable shrinking sheet has been investigated. The analytical solution arising differential system has been computed by the Adomian Decomposition Method (ADM). Variations of interesting parameters on the velocity are observed by plotting graphs. [3]

**MHD Flow of Fluid over a Rotating Inclined Permeable Plate with Variable Reactive Index**

MHD free convection, heat and mass transfer flow over a rotating inclined permeable plate with the influence of magnetic field, thermal radiation and chemical reaction of various order has been investigated numerically [4]

**Natural Convective Mass Transfer MHD Flow of Chemically Reactive Micropolar Fluid Past a Vertical Porous Plate**

Magnetic field effects on a free convective mass transfer flow of chemically reactive micropolar fluid over a vertical porous plate are investigated in this work. Suitable similarity transformations are used to derive a set of nonlinear ordinary differential equations governing the flow. Analytical solution of the dimensionless problem is obtained using perturbation technique. The velocity, angular velocity and concentration profiles, which are controlled by a number of parameters, are presented graphically. Based on these graphs the conclusions are depicted, and the obtained results are tested for their accuracy. [5]
