In this paper Dufour, Radiation absorption, Chemical reaction, and viscous dissipation effects on Unsteady Magneto Hydrodynamic free convective Casson fluid flow through a semiinfinite vertical Oscillatory porous plate of time dependent permeability with Hall and Ion-Slip Current in a Rotating System was investigated. The dimensionless governing equations for this investigation are solved analytically by using multiple regular perturbation law. The effects of different parameters on velocity, temperature and concentration fields are shown graphically. With the aid of these, the expression for the skin friction, Nusselt number and Sherwood number profiles was done with the help of tables. It was found that as the Ion-slip parameter increases the Velocity and temperature profiles decreases but the velocity and temperature decrease with increases in Hall current parameter. Dufour effect and thermal radiation increases it leads to increase in both velocity and temperature. However an increase in both chemical reactions, Schmidt number, leads to decreases in concentration.

In the present study, the influence of Hall and ion-slip current on steady magnetohydrodynamics mixed convective, Ohmic heating, and viscous dissipative Casson fluid flow over an infinite vertical porous plate in the presence of Soret effect and chemical reaction are investigated. The modeling equations are transformed into dimensionless equations and then solved analytically through the multiple regular perturbation law. Computations are performed graphically to analyze the behavior of fluid velocity, temperature, concentration, skin friction, Nusselt number, and Sherwood number on the vertical plate with the difference of emerging physical parameters. This study reflects that the incremental values of Casson fluid parameter and Schmidt number lead to reduction in velocity. However, fluid velocity rises due to enhancement of ion-slip parameter but an opposite effect is observed in case of Hall parameter. In addition, the Sherwood number declines with enhancing dissimilar estimators of the chemical reaction, Schmidt number, as well as Soret number.

This paper deals with the flow of an incompressible couple-stress fluid containing gyrotactic microorganisms in a channel with expanding or contracting porous walls. The bio-convection in couple stress fluid is advantageous to study various kinds of physical problems since couple stress fluid model can explain the rheology of various complex fluids, such as polymeric suspension, lubricants, liquid crystals, and blood. The governing equations are reduced to a system of non-linear ordinary differential equations using similarity transformations, linearized using successive linearization method and then solved using the Chebyshev collocation method. The influence of couple stress fluid parameters and other pertinent physical parameters on the motile microorganism distribution and density number of motile microorganism is examined.
