Internal Wave Generation and Near-Resonant Interactions: Theory and Applications
(University of Waterloo, 2011-04-29)Near-resonant triad interactions and wave generation theory are investigated for continuously stratified fluids. Interaction equations are derived for spatially-varying wave trains under the inviscid Boussinesq approximation. ... -
A Model for Shear Response in Swimming Plankton
(University of Waterloo, 2016-08-11)The responses of zooplankton to the hydrodynamic variables of their environment, such as shear, are not well understood. We examine stochastic swimming models of the run and tumble type for plankton moving in a velocity ... -
Numerical Simulations of Internal Solitary and Solitary-Like Waves: Wave Interactions and Instabilities
(University of Waterloo, 2019-05-31)Internal solitary and solitary-like waves (ISWs) are commonly observed in stably stratified fluids such as the Earth's atmosphere and oceans. As these waves interact with other physical processes and/or move through a ... -
Poincare Waves and Kelvin Waves in a Circular Lake
(University of Waterloo, 2009-01-28)When wind blows over a stratified lake an interface tilt is often generated, and internal waves usually appear after the wind stops. Internal waves in lakes are studied in many literatures, but most assume a hydrostatic ... -
Simulation of the Navier-Stokes Equations in Three Dimensions with a Spectral Collocation Method
(University of Waterloo, 2011-05-13)This work develops a nonlinear, three-dimensional spectral collocation method for the simulation of the incompressible Navier-Stokes equations for geophysical and environmental flows. These flows are often driven by the ... -
Spectral analysis of internal waves generated by tide-topography interaction
(University of Waterloo, 2007-08-21)Internal waves in the deep ocean play a deciding role in processes such as climate change and nutrient cycles. Winds and tidal currents over topography feed energy into internal waves at large scales; through nonlinear ... -
Stratified Flow Over Topography: Steady Nonlinear Waves, Boundary Layer Instabilities, and Crater Topography
(University of Waterloo, 2013-11-29)This thesis investigates several aspects of stratified flow over isolated topography in ocean, lake, and atmospheric settings. Three major sub-topics are addressed: steady, inviscid internal waves trapped over topography ...
