Three-dimensional buoyancy-driven flows in cylindrical cavities with differentially heated endwalls. Part 1. Horizontal cylinders

Abstract

Numerical solutions of the three-dimensional equations for buoyancy-driven flows in cylinders with differentially heated endwalls have been obtained by a finite-difference method. Special attention has been devoted to the complex three-dimensional flow structures arising in horizontal cylinders for configurations relevant for crystal growth by vapour transport. The characterization of the transition between the core-driven regime and the boundary-layer-driven regime is considered with the properties of the main flow and also the transverse flow.
