Convection of Strong Stratified Colloidal Suspension

The сonvective instability and nonlinear flows of a colloidal suspension in horizontal layer are studied in the case when the layer height is comparable with the sedimentation length of nanoparticles. The numerical analysis is carried out within the Boussinesq approximation on the basis of a modified model that takes into account the dependence of a thermal diffusion flux on the local value of impurity concentration. The stability borders and...
