Numerical simulations of buoyancy driven flows in cylinders and cavities for vapour crystal growth
Résumé
The paper reports about numerical works carried out by the authors at I.M.F.M. in the group of Numerical Fluid Mechanics. The common objectives of these works are related to the analysis of fluid dynamics in closed tube methods employed in crystal growth from vapours. Several numerical methods are considered and the solutions are discussed with respect to the results obtained with different approaches of the problem as the asymptotic theories, the stability analyses and the experiments. Some groups were associated in relation with these approaches and also the development of the numerical methods, finite difference and spectral methods. They are the groups of Prof. G. De Vahl Davis at University of New South Wales-Australia, Prof. F. Rosenberger at University of Utah-U.S.A. (with Dr. G.H. Schiroky, B.L. Markham, A.C. Hurford..), Prof. R. Sani at University of Colorado-Boulder-U.S.A. (with G. Hardin), Prof. M.G. Velarde at U.N.E.D.-Madrid-Spain (with E. Crespo), Dr. R. Peyret at Université de Nice-France (with Dr. J. Ouazzani and J.M. Lacroix).
