The hydrodynamics of two-dimensional oscillating flows over ripples: the effect of asymmetries in ripple shape and currents

Wickramarachchi, Subasha (University of Waterloo, 2017-04-28)

The research presented in this thesis involved consideration of three increasingly asymmetric oscillatory flows over two ripple profiles, one of which is asymmetric and represents a small deviation from a symmetric ripple. ...
Numerical Simulation of Surface Waves using Meshfree Methods

Wickramarachchi, Subasha (University of Waterloo, 2009-04-27)

Smoothed Particle Hydrodynamics (SPH) is a Lagrangian-based numerical method used for simulating problems in fluid and solid mechanics. In this thesis, a basic introduction to particle and Smoothed Particle (SP) approximations ...
