Abstract
An apparatus for generating a stream in a body of water has at least one cylinder installed under water, and a water-jet pump housed in the cylinder. The pump draws water in through one end of the cylinder and produces a stream of water accelerated by a driving fluid supplied from an external source. The stream is discharged through another end of the cylinder to promote a flow in the body of water.
Claims7
A method of generating a stream of water in a body of water, said method comprising:
- providing an apparatus including at least one tubular member having opposite open ends, one of which ends defines an inlet and the other of which ends defines an outlet, and a nacelle disposed within the tubular member, the nacelle having an inlet port facing towards said inlet of the tubular member and an outlet port facing toward the outlet of said tubular member and a nozzle open to the interior of the nacelle at a location between said ports and directed towards the outlet port;
- submerging the apparatus in a natural body of water;
- and
- supplying driving fluid to said nozzle under pressure while the apparatus is submerged such that the driving fluid is jetted from the nozzle towards the outlet port of the nacelle to form an accelerated stream within the tubular member which induces a portion of the natural body of water to flow as a stream relative to the remainder of the natural body of water and through the tubular member.
