These studies concern the forced or convective flows and their control in connection with material processing. Indeed, the flows occuring in the melt during material processing (semi-conductors and alloys) have a great influence on the repartition of the components in the solidified material (segregation phenomena). Moreover, when the flows are time dependent, they are the cause of composition defects appearing as concentration striations. A better knowledge of the flows in the melt and the control of these flows are necessary for the improvement of material quality.
The different studies in this domain, rather fondamental or with a more applied vision, are presented in the successive articles below. For each topic, we give the main results and the corresponding publications. All the publications on these different topics are then given at the end.
