AXIAL JET MIXING OF ETHANOL IN SPHERICAL CONTAINERS DURING WEIGHTLESSNESS

摘要

An experimental program was conducted to examine the liquid flow patterns that result from the axial jet mixing of ethanol in 10-centimeter-diameter spherical containers in weightless¬ness. Complete liquid circulation flow patterns were easily established in containers that were less than half full of liquid, while for higher liquid fill conditions, vapor was drawn into the inlet of the simulated mixer unit. Increasing the liquid-jet velocity or lowering the posi¬tion at which the liquid jet entered the container caused increasing turbulence and bubble formation.
