Study on Oscillatory Mechanism of Solutocapillary Convection and Influence of Aspect Ratio on Flow Characteristics during Crystal Growth

A numerical simulation has been conducted to investigate the oscillatory mechanism of a solutocapillary convection and influence different aspect ratios on flow characteristics in liquid bridge. The SIMPLE algorithm is applied figure out Navier-Stokes equation concentration diffusion staggered grids, level set approach with conservation mass used acquire surface deformation are analyzed detail, including distributions concentration, velocity, transverse displacement free at upper corner intermediate height Moreover, effects ratio stability onset time oscillations for velocity have also investigated. results show that essence result coupling oscillation surface. origin region oscillation, which an important impact overall characteristics. Within definite range bridge, lower height, more stable weaker oscillation. There complex relationship between
