A method and device for capturing bubble polymerization process

Abstract

The invention provides a device for capturing the bubble polymerization process, which includes a bubble polymerization generating device and photographing and data processing equipment for recording and analyzing the bubble movement process in the bubble polymerization generating device; the bubble polymerization generating device includes a sealed filling A liquid container, a liquid filling pipe, a number of dripping pipes and an air inlet pipe. The liquid filling pipe is installed on the upper part of the liquid filling container and communicates with the interior of the liquid filling device. A valve is arranged on the liquid filling pipe; the dripping pipe The opening is installed at the bottom of the liquid-filled container downwards, and is used to discharge the liquid in the liquid-filled container under the action of gravity, and a regulating valve is installed on the dripping tube; the air inlet pipe communicates with the dripping tube as the A branch pipe whose open end is open to the atmosphere and whose height is higher than the level of the liquid in the liquid-filled container. The device of the invention can obtain air bubbles of different sizes and speeds, and the formed air bubbles are relatively stable and difficult to break, and the whole dynamic polymerization process lasts for a long time, which reduces the requirement for a shooting camera.

Description

technical field [0001] The invention relates to the technical field of measuring the dynamic behavior of bubbles in fluid dynamics multiphase flow, and is suitable for capturing and recording the dynamic behavior of bubbles and bubble aggregation, especially for the collision and contact between two bubbles, and the combination of two bubbles into one Capture and recording of a bubble dynamic process. Background technique [0002] Gas-liquid two-phase bubbly flow exists widely in industry and nature. Therefore, a deep understanding of the dynamic behavior of bubbles (such as the collision and aggregation process of bubbles) is crucial for understanding and enriching the hydrodynamic characteristics of gas-liquid two-phase bubbly flow and improving It is of great significance to control the heat transfer and mass transfer efficiency of bubbly flow. Although various forms of optical photographing and recording systems have been developed, it is very difficult to capture the d...
