Abstract
A 2 cSt silicone oil (Pr=28) liquid bridge of 15.0 mm length L and 3.0 mm radius r (aspect ratio A=L/r=5) was established under microgravity during the flight of the sounding rocket MAXUS-4. Four different temperature differences Delta T=7, 9, 10, and 12 K were applied between the ends, each for sufficient time to reach steady-state thermocapillary flow conditions. The aim of the experiment-to observe the onset of hydrothermal waves and to measure their features such as the wave phase speed and the angle between the wave vector and the applied temperature gradient-was reached. We used microgravity in this experiment in a twofold manner: (1) a liquid bridge with A=5 can be established only under microgravity; (2) it was possible to study hydrothermal waves without the influence of gravity and without the aspect ratio restrictions at normal gravity.
