Abstract

A model for radiation-induced natural convection in a water-filled wedge is described in [3]. With this model there is the potential for a thermal instability [2]. Flow visualisation revealed the primary form of the instability [5], which was confirmed by numerical simulations [4]. A corresponding scaling analysis has identified the critical condition and the controlling parameters as the Prandtl number Pr, the Grashof number Gr, and the cavity aspect ratio A [6].
