Water flow regulator for irrigation canals

A distinctive feature of the irrigated systems Russian Federation is a large area areas and significant length irrigation canals. With massif on small canals, use electricity to regulate throughput network hydraulic structures economically ineffective. Preference given means automation water supply. Regulation structure based laws fluid flow within it. On canals in Russia, as world practice, water-operated gates are widely used. One disadvantages such moving metal parts sensors, which reduce operational reliability structures. new regulator proposed, action injection effect. Compression by physical elements was replaced circulation surplus supply between outlet section downstream. The built into pressure drop high low order channels. Regulating tubular automatically begins after shutting down one or more sprinklers that take from lower canal. After turning operation, restores original throughput. Using theory jet pumps, method has been developed for theoretical determination main characteristics regulator. These include size nozzle velocities streams. derivation dependencies classical equations mechanics; considered quasi-one-dimensional. obtained calculated were verified using numerical modeling. data experiment good agreement with dependences. Further optimization controller can be performed changing its geometric parameters.
