| Popis: | Theoretical and numerical solutions are proposed for the prediction of the thermal and solutal convection in a long horizontal ampoule in the presence of local temperature gradients at the walls as involved in the multizone furnace applications. A finite difference method is used for a Boussinesq fluid in a two-dimensional cavity with modelized wall temperature gradients, locally applied. The results are carried out without and with an interfacial mass flux at the source and sink. A seed has been also modelized at the horizontal walls. |
