Abstract
The influence of various convective levels in a melt on a S/L interface is experimentally investigated in a continuous way from pure laminar flows to turbulent ones. Simple description in the Fourier space makes apparent a chaotic and oscillating zones alternance when thermal field is progressively increased. A classical theoretical transition towards the chaos (Feigenbaum mechanism) seems to be identified. Influence on crystal growth is finally examinedKeywords
