The movement of three-phase gas bubbles under the influence of their electric field
The results of an experimental study of the flow of a hydrophobic liquid between non-concentric cylinders are presented. It is shown that with a small gap between the cylinders and their counter rotation, in the area of flow expansion, gas cavitation of dissolved gas and steam of a small impurity of water can be observed. After suspending the flow, water vapor condenses with the formation of three-phase cavitation bubbles and microdrops of water at the gas-liquid interface. It was found that when surfaced, three-phase bubbles have their own magnetic field. The leading role of such bubbles on the behavior of smaller gas bubbles is shown. Based on the analysis of the interaction of bubbles, the magnetic field of a three-phase bubble is reconstructed.

Представлены результаты экспериментального исследования течения гидрофобной жидкости между неконцентрическими цилиндрами. Показано, что при малом зазоре между цилиндрами и встречном их вращении, в области расширения потока, может наблюдаться газовая кавитация растворенного газа и паровая небольшой примеси воды. При остановки движения потока, водяной пар конденсируется с формированием трехфазных кавитационных пузырьков и микрокаплями воды на границе раздела газ-жидкость. Обнаружено, что при всплытии трехфазные пузырьки обладают собственным магнитным полем. Показана лидирующая роль таких пузырьков на поведение более мелких газовых пузырьков. По анализу взаимодействия пузырьков сделана реконструкция магнитного поля трехфазного пузырька.
