AbstractWe are interested in convection occuring during crystal growth from melts in a floating zone model. In this case, convection is mainly induced by the Marangoni effect. Our analysis shows effects of some phenomena such as differential rotation and buoyancy. Numerical computations were performed with a finite element code. Different steady thermocapillary flows are obtained by varying the following significant parameters: rotation velocity (rotation Reynolds number), temperature gradient conditions (Grashof and Bond numbers), surface tension gradient (Marangoni and capillary numbers), all of them relevant in practical crystal growth situations.
