Abstract

Hydraulic reaction turbine comprising, a runner, a draft tube (1) downstream of the runner, and - injection means (4,10) for introducing water into the draft tube in order to reduce pressure fluctuations therein, with one or more openings (10) in the draft tube wall (1a) adapted to substantially evenly distribute injected water in the axial and/or circumferential direction of the draft tube (1).
