MASTER THESIS
Background and objective
A good understanding of transient flows in pipes
and ducts is essential to ensure safe operation
of hydropower plants. Forced transients can be
used actively to improve this understanding by
means of frequency response measurements.
Experiments involving such transients will be
done by Flow Design Bureau AS in a closed flow
loop. The purpose of this master thesis is to
assist them in their work, considering design,
modelling and analysis related aspects.
