Marangoni convection in half-zone liquid bridge

Marangoni flow, which is driven by unbalanced surface tension caused by tem perature or concentration gradient, plays an important role in mass and hea t transport in crystal growth of floating zone. Half-zone model, which is s implified from floating zone model, is one of typical models to the study o f Marangoni convection. Recent numerical and experimental studies on Marang oni convection in half-zone are reviewed, The importance of direct numerica l simulation is stressed.
