Studies on the Marangoni flow of molten silicon are reviewed. Marangoni flow of low Pr number fluids, such as molten silicon, have been carried out mainly experimentally from the viewpoint of application. Since, for molten silicon, it is rather difficult to attain small Marangoni number, a partially confined structure has been employed both for experimental and numerical studies. The critical Marangoni number Mac3 is an important criterion from the application viewpoint. Flow instability has been studied experimentally; basic relationship between an aspect ratio and azimuthal wave number is sustained even under the large Marangoni number case.
