To study the effects of gravity on thermocapillary convective phenomena, observations were made of thermocapillary convection in different lengths of silicone oil liquid bridge that simulated a half floating zone under normal gravity (1g) and microgravity (μg) conditions in a free-falling capsule. Thermocapillary convection is dominant at the interface. However, in bulk, gravity has an effect on the...
An empirical study was conducted to investigate convection in a silicone oil liquid bridge of dimensionless volume V/V o between hot and cool disks under both normal gravity (1g) conditions and under microgravity (μg) conditions in free-fall. The study explored the influences on the critical temperature difference (ΔT c ) at which thermocapillary convection changes from steady to oscillatory,...
