Numerical calculations of the flow caused by thermocapillary forces at the free surface in NaNO 3 and Si melts in an open boat geometry have been carried out. The results agree well with measured flow velocities in model experiments for crystal growth configurations with NaNO 3 melts. For Si melts a transition to a more complicated multiple eddy flow occurs. The projection‐iteration method used for the calculations is much more effective than the finite difference methods applied until now and is especially advantageous for more complicated flow patterns.
