Abstract
The dynamics of the Taylor vapor bubble rise in a circular (16 mm cross-sectional diameter) and annular (25 and 16 mm cross-sectional diameters) channel at saturation pressure was experimentally studied. The bubble formed during boiling of superheated degassed liquid. It was found that the movement velocities of its front and rear surfaces are variable and depend on the rise regime, its position in the channel, and the previous rise dynamics. It is shown that this behavior is determined by the spatiotemporal distribution of liquid temperature at the bubble boundary. Based on the obtained results, a map of rise regimes was plotted, linking the nature of movement with the magnitude of liquid superheating near the vapor bubble surface.
期刊介绍：
The journal Thermophysics and Aeromechanics publishes original reports, reviews, and discussions on the following topics: hydrogasdynamics, heat and mass transfer, turbulence, means and methods of aero- and thermophysical experiment, physics of low-temperature plasma, and physical and technical problems of energetics. These topics are the prior fields of investigation at the Institute of Thermophysics and the Institute of Theoretical and Applied Mechanics of the Siberian Branch of the Russian Academy of Sciences (SB RAS), which are the founders of the journal along with SB RAS. This publication promotes an exchange of information between the researchers of Russia and the international scientific community.
