Abstract

Numerical results are presented from a study to determine flow and temperature fields in a vessel heated from below by a line source and cooled from above. Effects of key parameters on the thermal plume structure and heat transfer rates are discussed in the laminar regime. Consideration is given to transition from laminar to chaotic flow in a vessel of square cross-section. A sequence of instabilities is discussed according to results of direct simulations of time-dependent regimes.
