Description

technical field [0001] The invention belongs to the technical field of two-phase flow experiments, and in particular relates to a solid-liquid two-phase flow observation system. Background technique [0002] At present, with the development of ports, waterways, water conservancy and coastal city construction, the engineering conditions involved in dredging enterprises are also more complicated. For dredging construction enterprises, the level of technology has become an important issue directly related to the survival and development of enterprises. The research on solid-liquid two-phase flow technology is an important part of dredging technology and the core technology in dredging engineering, which determines the production efficiency, project schedule and project cost. Solid-liquid two-phase flow technology is a technology based on semi-theory and semi-experience, and its research results are heavily dependent on experimental testing techniques. The establishment of a h...
