В статье рассматриваются особенности циркуляционных течений и их использование в вихревых водосбросах при проектировании высоконапорных гидроузлов. Приводятся результаты специальных лабораторных исследований, при проведении которых зафиксированы определенные формы движения, сменяющие друг друга в определенной последовательности. В опытах с закрученной струей обнаружены аналогичные структуры, а также наличие области с обратным течением в центральной части и ее влияние на интегральные характеристики циркуляционного потока в трубе.
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.
