Abstract
The invention discloses a multiphase flow vertical-type water hole with a bi-directional flowing function. The multiphase flow vertical-type water hole comprises a power section, a backflow section, alower rectifying section, a lower diameter-variable section, a work section, an upper diameter-variable section, an upper rectifying section and an upper tank. In work, a second water pump is closed,a first water pump is started, a fluid in the water hole flows to the lower rectifying section, the lower diameter-variable section, the work section, the upper diameter-variable section and the upper rectifying sectionsequentially along the backflow section and then enters the upper tank for closed circulation; or the first water pump is closed, the second water is started, the fluid in the water hole flows to the upper rectifying section, the upper diameter-variable section, the work section, the lower diameter-variable section and the lower rectifying section sequentially along the upper tank and then enters the backflow section for closed circulation. According to the multiphase flow vertical-type water hole, the mode that the first water pump and the second water pump are arranged inparallel is adopted, the movement direction of the fluid is conveniently and rapidly converted; and water replenishing connecting pipes and particle solution connecting pipes are evenly distributed on the lower diameter-variable section and the upper diameter-variable section, the influences of flowing separation on the experimental result are prevented from water replenishment, and through adding of bubbles and particles, multiphase flowing is achieved.
