Problems solved by technology
The research on the behavior of bubbles in a static vessel does not consider the additional inertial force caused by sway conditions; the research on the behavior of bubbles in flow pipes under swaying conditions is affected by the flow, and the motion of the flow channel is the superposition of lateral motion and longitudinal motion, The influencing factors are complex; none of them can accurately reveal the influence of sway conditions on bubble behavior

Description
technical field [0001] The invention belongs to the field of two-phase flow and bubble dynamics, and in particular relates to an experiment and image automatic acquisition system used for research on bubble behavior under swaying conditions. Background technique [0002] Bubble behavior widely exists in ship thermal power plants and ship nuclear power plants, and will affect the flow and heat transfer characteristics of the system. During the motion of the ship, the behavior of the bubbles is also influenced by the sway conditions caused by the waves and the ship's own maneuvering. Therefore, it is of great engineering significance to study the behavior of bubbles under sway conditions. At present, scholars at home and abroad have done a lot of research on the bubble behavior, but most of these studies are aimed at the bubble behavior in a static container, or the bubble behavior in a flow pipeline under rocking conditions. The research on the behavior of bubbles in a stat...
