The numerical simulation of natural convection in the Hale-Shaw cell during horizontal Bridgman solidification reveals that the convection presents even for the very thin cell. The effects of the horizontal temperature gradient,G, thickness of the cell,H, temperature difference between the top and bottom of the cell, and other parameters have been studied. These findings have been confirmed by experiments through direct observation and measurement of convection in the cell containing succinonitrile transparent model alloy.
