Computer aided floating zone growth of Germanium-Silicon crystals in a resistance heated multi-zone furnace

In this work a technologically state-of-the-art growth furnace <br>-- the FMF-module (Floating Zone Furnace with Rotating Magnetic <br>Field) -- is under development for crystal growth experiments on <br>the International Space Station. By using global simulations and <br>the inverse modeling method, its optimal design and its <br>performance could be obtained. By means of direct numerical simulations, the influence of solutal Marangoni convection on species transfer in a floating <br>zone could be qualitatively explained. The instability mechanism <br>of thermocapillary convection in a low Pr floating zone could be <br>attributed to the interaction of buoyancy convection and surface <br>flows. The direct numerical simulations were based on a full zone <br>model.
