The embodiment of the present application provides a method for determining the interaction force between droplets, a two-phase flow control method, and equipment. The method for determining the interaction force between droplets includes: obtaining an image captured by a photographing device connected to an amplification device under a light source An image of the droplet to be tested, wherein the droplet to be tested includes a first droplet and a second droplet, the first droplet is suspended in a transparent container, and is connected to the existing droplet in the transparent container The second droplets approach each other; according to the image, determine the droplet profile of the first droplet; according to the image and the droplet profile, determine the distance between the first droplet and the second droplet The interaction force between droplets can be accurately determined, and the above method does not require expensive measuring instruments and high operating skills, and is cheap, easy to operate, and easy to popularize, which is conducive to the subsequent research on two-phase flow .
Description
technical field [0001] The embodiments of the present application relate to the technical field of two-phase flow, and in particular to a method for determining the interaction force between droplets, a method and equipment for controlling two-phase flow. Background technique [0002] With the development of social economy and science and technology, chemistry, chemical industry, petrochemical, medicine, food and other fields have been developing rapidly, and the application of two-phase flow is inseparable from the above fields. Two-phase flow refers to a flow system composed of two-phase substances with at least one phase being fluid. It is the most common viscous fluid flow involved in the completion of interphase mass transfer and reaction processes in production, such as heat transfer when there is a phase change , gas absorption in column equipment, liquid distillation, liquid extraction, and chemical reaction processes in stirred tanks or bubble columns, etc., all inv...
