A novel method for simulating experimentally the low Prandtl                    number natural convection typical of semiconductor melts will be                explored.  Conventional fluids with Prandtl number near unity                   will be subjected to thermal radiation to thicken the thermal                   boundary layer.  Visualization through streak photography will be               used to reveal flow patterns simulating semiconductor melt                      convection, since such visualization is difficult to impossible                 in actual melts.  This will contribute to understanding and                     control of semiconductor crystal growth for more homogeneous                    semiconductor crystals.
