AbstractThe critical Marangoni number is determined by the optical method, a new parameter describing the free surface shape is sensitive to the onset of oscillation. The experiments are performed for half floating-zone with either a upper rod heated (URH) or a lower rod heated (LRH). The results agree with the instability analyses of buoyancy influence (see, for examples, /1–3/).
