摘要
In their study of time-dependent thermocapillary convection in cylindrical liquid bridges Velten et al. [Phys. Fluids A 3, 267 (1991)] determined the azimuthal flow structure by measuring the phase of the temperature oscillations at three different azimuthal angles. Their explanation of the data in terms of modes with wave number m = 0 is not always compatible with the normal-mode decomposition of the disturbances at the threshold. A new interpretation is given that explains the peculiar phase measurements in terms of pairs of m not-equal 0 counterpropagating waves.
