Abstract

In support of the Surface Tension Driven Convection Experiment planned for flight aboard the space shuttle, tests were conducted under reduced gravity in the 2.2-second drop tower and the 5.0-second Zero-G facility at the Lewis Research Center. The dynamics of controlling the test fluid, a 10-centi Stoke viscosity silicone fluid, in a low gravity environment were investigated using different container designs and barrier coatings. Three container edge designs were tested without a barrier coating: a square edge, a sharp edge with a 45-deg slope, and a saw-tooth edge. All three edge designs were successful in containing the fluid below the edge. G-jitter experiments were made in scaled-down containers subjected to horizontal accelerations. The data showed that a barrier coating is effective in containing silicone fluid under g-levels up to 10•1 g0.
