“…Recent developments mention an interest of 3D simulations for cavities heated from bellow and especially involved on directional solidification [7]. The increasing interest in that field refers to the interaction between solid and liquid phases in terms of morphological resulting structures (kinetics of growth, composition and shape of the interface).…”

“…Computational results presented in these papers were used to analyze a dynamic regime interacting with the solid/liquid transition. Recent extensions to three-dimensional calculations [6] are limited to high Prandtl number and do not cover the extensive situations encountered in real crystal growth. This study focuses on the three-dimensional character of low Prandtl number flows and on the symmetry breaking phenomena which can produce some unsteadiness in the flow and consequently perturb the solid/ liquid interface shape and dopant distribution.…”

International audienceA computational model is developed to investigate three-dimensional fluid flow instability and transition to unsteadiness. The simulated domain corresponds to a parallelepiped configuration which is a restriction to the fluid phase of commonly used configurations in crystal growth (viz. Bridgman configuration). In the present work, this problem is studied using three-dimensional simulations and focuses on symmetry breaking and transition to unsteadiness occurring for a low Prandtl number fluid (Pr = 0.01). Three-dimensional simulations presented thus overcome the limitation of the two-dimensional approach. It has been found that the initially steady symmetric flow in the three-dimensional case becomes asymmetric for lower Ra number than for the two-dimensional case. The breaking in symmetry occurs firstly in the transverse plane. For the relatively low Ra number we still have no intensification in the global heat transfer but it appears that the heat transfer increases locally on the bottom and decreases on the vertical active walls. The classical spiral flows typical characterizing the three-dimensional effect (in the third direction) are also identified
