Soret-driven ferro thermohaline convection

Soret-driven thermoconvective instability in multicomponent fluids has wide applications in heat and mass transfer estimations. In ferrofluids, three components, namely, core, surfactant and carrier fluids, coexist. In this paper, an attempt is made to obtain the condition for the onset of thermoconvective instability due to the Soret effect. Both stationary and oscillatory instabilities have been investigated. The principle of exchange of stability is used to determine mode of instability. A linear stability analysis is used. The results are presented numerically and graphically.
