MASTER THESIS
Background and objective
The purpose of this master thesis will be
to perform experimental and one-way FSI
investigation on a hydrofoil in an unsteady flow
field.
Due to varying demand for power, hydro turbines
are run with frequent load variations which
cause harmful vibrations and has a negative
influence on the flow field behavior.
The shape of the trailing edge of the turbine
blades influences the vortex shedding behind
the blades at particular frequencies. In this
work, experimental data will be compared with
a numerical investigation, and an analysis of the
effect of the shape of the trailing edge on the
vortex shedding frequencies will be performed.
