Abstract: | The thermal convection in a square cavity filled in with a viscoplastic liquid is considered as a model example to illustrate the mechanism of convection termination. It is shown that at low Rayleigh numbers, the stopping of convection corresponds to a limit point in the parameter space. Using this observation, we propose a heuristic numerical approach to calculate the critical Rayleigh numbers. |
