Abstract
This paper aims to provide an insight into the aspects of turbulence anisotropy in the di- rectional solidfication (DS) method, which is widely used for the growth of photo-voltaic silicon. In DS crucibles, the melt flow is usually stratified due to strong temperature gradients and this leads to anisotropy of ow and turbulence, which is often neglected in turbulence models used in engineering applications. In experimental measurements, a transition between strong and weak mixing regimes is found. The numerical simulations results provide quantitative measures for anisotropy and vertical heat transfer intensity within the range of different Richardson numbers (0.1 - 40).
