Background
Over the last few years, reasonably priced
methods for measuring rock-blasted tunnel
geometries with laser scanners have become
available. This information can be used to find
tunnel friction factors. The Research Council of
Norway has made a contribution to a project in
which selected tunnels are tested in a hydraulic
laboratory. Here, friction loss, water velocity and
turbulence are measured.
At the same time, it is desirable to find these
quantities using a three-dimensional numerical
model solving Navier-Stokes’ equations. The
latter is the topic for thismaster thesis. The CFD
program OpenFOAM will be used.
