INVESTIGATION ON A SIMULATION-MODEL OF FLOATING HALF ZONE CONVECTION .2. EXPERIMENT

A simulation model of floating half zone with non-uniform temperature distribution at the upper rod and uniform temperature distribution at lower rod was discussed by numerical investigation in a previous paper . In the present paper, the experimental investigation of the simulati on model is given generally. The results of the present model show tha t the temperature profile is quite different and the critical applied temperature difference is lower than the one of usual model with same geometrical parameters in most cases. The features of critical Marango ni number depending on the liquid bridge volume are also different fro m the ones of usual model. (C) 1997 Elsevier Science Ltd.
