Features recirculating flow in hydro-cal facilities

At the article features of circulating currents and their use in vortex spillways are considered at design of high-pressure water-engineering systems. Results of special laboratory researches at which carrying out the certain forms of movement replacing each other in certain sequence are recorded are given. At the experiences with the twirled stream similar structures, and also area existence with a contraflow in the central part and its influence on integrated characteristics of a circulating stream in a pipe are found.
