Kurzfassung englisch:
Hydraulic model tests were conducted to evaluate the head-losses and flow conditions of
an asymmetrical throttle in a surge chamber system of an Austrian high-head power
plant. The asymmetrical throttle is situated at the beginning of the rising shaft of the
surge tank in one of the three branches of a T-shaped junction. Due to the asymmetrical
shape of the throttle it causes different head-losses between up- and downsurging water
levels.
Several hydraulic model tests with a scale of 1:21 were carried out under different flow
conditions to evaluate the head-losses. Due to the complex shape of the T-junction the
model was milled out of a plastic cube with the help of CNC.
Then, several CFD-simulations were conducted in order to evaluate under which circumstances
the CFD-simulation is able to give reasonable results.
