Thermosolutal convection in a heterogeneous fluid layer in porous medium in the presence of a magnetic field (Q1308897)

The thermosolutal instability in porous medium in a viscous, conducting, incompressible and heterogeneous fluid layer confined between two free boundaries is studied using linear theory, when the whole system is immersed in a uniform vertical magnetic field. The existence of stationary, oscillatory and non-oscillatory modes is discussed. A variational formulation of the problem is also established and numerical computations are done to study the influence of various parameters.
