Three dimensional free-surface flow over arbitrary bottom topography
Nicholas R. Buttle, Ravindra Pethiyagoda, Timothy J. Moroney +1
We consider steady nonlinear free surface flow past an arbitrary bottom topography in three dimensions, concentrating on the shape of the wave pattern that forms on the surface of…
Efficient computation of two-dimensional steady free-surface flows
Ravindra Pethiyagoda, Timothy J. Moroney, Scott W. McCue
We consider a family of steady free-surface flow problems in two dimensions, concentrating on the effect of nonlinearity on the train of gravity waves that appear downstream of a d…
Extending fields in a level set method by solving a biharmonic equation
Timothy J. Moroney, Dylan R. Lusmore, Scott W. McCue +1
We present an approach for computing extensions of velocities or other fields in level set methods by solving a biharmonic equation. The approach differs from other commonly used a…
Time-frequency analysis of ship wave patterns in shallow water: modelling and experiments
Ravindra Pethiyagoda, Timothy J. Moroney, Gregor J. MacFarlane +2
A spectrogram of a ship wake is a heat map that visualises the time-dependent frequency spectrum of surface height measurements taken at a single point as the ship travels by. Spec…
