AbstractThe paper illustrates the experiment, performed on TEXUS 9, to simulate the thermofluidynamic behavior of a floating zone in a Micro-Gravity Environment (MGE). The experiment (during the six minutes of microgravity) gave much information that allowed a quantitative evaluation of the Marangoni flow at unsteady conditions (during zone heating and cooling) and at different flow regimes (i.e. laminar, oscillatory and nonperiodic). Flow velocities and heat transfer into the cold disc are evaluated. The computerized equipment necessary for data elaboration is described. The experimental results are compared with a numerical simulation of the floating zone.
