Nonlinear waves in pipes and channels

Atle Jensen
University of Oslo
Breaking waves is a topic of hydrodynamic wave theory for which our insight is still very limited. Qualitative description and classification are found in the literature, but a number of aspects and applications for breaking and steep nonlinear waves still await proper analysis. In mid ocean breaking waves are important for momentum transfer from wind to ocean currents as well as mixing of the surface layers. From an engineering point of view plunging breakers and extremely steep waves may present extreme loads on structures and vessels. Results from experiments and numerical simulations of steep waves in a wave tank will be presented together with nonlinear waves in a gas/liquid pipe.
