Some results in the nonlinear stability for rotating Bénard problem with rigid boundary condition

Paolo Falsaperla, Andrea Giacobbe, Giuseppe Mulone


The scope of this article is to expose the stabilizing properties of rotation and solute gradient for the Bénard problem with (at least one-sided) rigid boundary conditions. We perform a linear investigation of the critical threshold for the rotating Bénard problem with a binary fluid, and we also make an investigation with a Lyapunov function for the particular problem of a rotating single fluid. In all the these cases an increase of the Taylor number has stabilizing effects.
