Abstract: The double diffusive effect of ferro thermohaline convective instability in a ferrofluid, saturating a rotating porous medium heated from below and salted from above, has been studied using Brinkman and Darcy models. The effect of salinity has been incorporated in the magnetization and density of the ferrofluid. Linear stability analysis is carried out. The onset of thermohaline convection is analyzed both by stationary as well as oscillatory modes. In all cases it is found that the porous medium of small permeability and large rotation tend to stabilize the system. It has been observed that stationary mode is favorable for Darcy model whereas for Brinkman model, possibility of oscillatory mode of instability cannot be ruled out. It is also found that the ratio of mass transport to heat transport decides the stabilizing factor. Numerical computations are made and are illustrated graphically.
