The influence of the hydrodynamic environment on the growth phenomena of large potassium dihydrogen phosphate (KDP) crystals has been investigated in a three vessel system. Special attention was paid to the onset of inclusion formation. Flow visualization experiments carried out in a wind tunnel showed that the flow formed at the rear (downstream) faces of the crystal (i.e. the wake) is a more or less closed circulation system. It appeared that veils of liquid inclusions are not a result of starvation in the laminar boundary layer, as suggested before, but of depletion in the closed wake at the rear.
