effect of sparse distribution pores in thermohaline convection in a micropolar ferromagnetic fluid

Thermoconvective instability in multi-component fluids has wide range of applications in heat and mass transfer. this paper deals with the theoretical investigation on a horizontal fluid layer of micropolar ferromagnetic fluid heated from below and salted from above saturating a porous medium subjected to a transverse uniform magnetic field using brinkman model. the salt is a ferromagnetic salt which modifies the magnetic field established. the effect of salinity has been included in the magnetization and density of the ferromagnetic fluid. a theory of linear stability analysis and normal mode technique have been carried out to analyze the onset of convection for a fluid layer contained between two free boundaries for which exact solution is obtained and the stationary and oscillatory instabilities have been carried out for various physical quantities. the results are depicted graphically and the stabilizing and destabilizing behaviors are studied.
