Dynamic behavior of liquids and gases in conical shells in a vibrational force field

An experimental study is made of specific features of the motion of the fre e surface of liquid in different conical shells, the formation, motion, and local accumulation of gas bubbles in the shells, and the character of rand om motion of the gas-liquid medium in a vibrational force field. It is esta blished that the liquid moves along the horizontal as well as the vertical axes under certain conditions when axisymmetric modes of vibration of the f ree surface are excited. The main characteristics of the dynamic behavior o f a gas-liquid medium in a compound conical shell having the form of a de L aval nozzle are examined for the case when the medium forms a nonlinear osc illatory "liquid-gas" system that is dynamically stable.
