|Title:||Effect of horizontal thermal gradient on double-diffusive ferroconvection|
|Abstract:||The effect of horizontal thermal and salinity gradients on ferroconvection of a double diffusive system subjected to two dimensional magnetic fields with compensating horizontal thermal and solutal gradients has been investigated. Assuming that the fluid layer is bounded by free boundaries, the conditions for the onset of stationary and oscillatory instabilities are established using linear theory and normal mode technique. Wide range of values of the ratios of horizontal and vertical gradients with respect to temperature, salinity and the cell size are considered. It has been found that the system stabilizes only through oscillatory mode for ratios of the temperature and salinity gradients which tend to make the cell size greater than 1. Stationary instability is found to occur for the ratios of the temperature and salinity gradients which tend to make the cell shape smaller than 1.|
