Abstract
Experiments have been performed to investigate the effect of a thermal boundary condition on the dynamic contact angle at compensated gravity conditions. Thermocapillary flows were generated between heated parallel plates. The data show that the Marangoni convection causes an increase of the apparent dynamic contact angle. A relation has been determined for the dynamic contact angle in dependence on the thermocapillary Reynolds number multiplied by the aspect ratio (L/D) an the ratio of the Weber number and the thermocapillary Weber number.
