Abstract
<p>A numerical simulation study was carried out to investigate the effect of thermo-solutal Marangoni convection on the flow patterns and the azimuthal wave number in a liquid bridge under zero-gravity. The liquid bridge in the model represents a three-dimensional half-zone configuration of the Floating Zone growth system. Three-dimensional field equations of the liquid zone, i.e. continuity, momentum, energy, and diffusion equations, were solved by the PISO algorithm. The physical properties of the silicon-germanium melt were used (Pr = 6.37×10-3 and Sc = 14.0). The aspect ratio Asp was set to 0.5. Computations were performed using the open source software OpenFOAM. The numerical simulation results show that the azimuthal wave number changes due to the competing contributions of thermal and solutal Marangoni convective flows.</p>
