Abstract
The bifurcation regimes of free convection in closed cavities with heating from below have been investigated numerically by many authors [1]. In the situations considered the equilibrium solution conditions were disturbed by only one factor, e.g. the inclination of the cavity to the vertical, the motion of one of the boundaries, a change in the equilibrium temperature distribution, etc. In this paper, the simultaneous influence of two factors that disturb the fluid equilibrium conditions, namely thermal radiation and a slight inclination of the cavity relative to the vertical, are investigated. It is shown that, for the simultaneous action of two destabilizing factors, a near-equilibrium solution is possible.
