Despiking Velocimetric Data with 2D ARMA Models and the Role of Impulse in Sediment Movement on Variable Bed Slopes
(University of Waterloo, 2015-01-14)The link between hydrodynamics and morphology of river bedforms is an ongoing field of research. Existing studies have been unable to provide a complete understanding of the physical conditions required to initiate sediment ... -
Effect of polymer additives on transitioning and turbulent boundary layers
(University of Waterloo, 2021-10-26)Injection of small quantities of polymer solutions in various internal and external turbulent flows can produce a substantial reduction of skin friction drag. This phenomenon, known as Toms phenomenon, has been actively ... -
Near-field Vortex Dynamics of Flows Emerging from a Rectangular Duct
(University of Waterloo, 2019-04-26)Shear layers and jets have motivated many researches to use experimental, theoretical and numerical methods for the better understanding of the fundamental physics and optimizing the flow characteristics that best suit ... -
Normal Mode Wave-Vortex Decompositions of Mesoscale Simulations
(University of Waterloo, 2017-08-18)The kinetic energy spectrum of the atmosphere has been well observed to exhibit a k^(-3) power law at synoptic scales with a transition to a shallower k^(-5/3) power law at the mesoscale. To better understand the mesoscale ... -
Progress on the application of the NS-alpha model to wall-bounded flows
(University of Waterloo, 2008-10-09)In this thesis we study the NS-alpha model of flow turbulence. In this model the closure arises through a modified nonlinearity. For the NS-alpha model currently used in published numerical studies, the parameter representing ... -
Strategically Coupled Inertial Flow and Interfaced Evolution (SCI-FIE) Models for Dissolution Mining
(University of Waterloo, 2022-08-23)Mineral dissolution or dissolution mining is a technology for underground mineral extraction. The space developed after the mining may be a desirable reservoir for the storage of natural gas and hydrocarbons or compressed ... -
Towards Large Eddy Simulation of Boundary Layer Flows at High Reynolds Number: Statistical Modeling of the Inner Layer
(University of Waterloo, 2006)Most fluid flows of practical interest involve and are affected by turbulence. One of the most promising computational methods for the prediction of turbulent flows is the so-called large eddy simulation (LES) methodology. ... -
Turbulence in stably stratified boundary layers
(University of Waterloo, 2020-11-26)In this thesis, turbulence dynamics for a stably stratified boundary layer is studied. The processes by which stable boundary layers are formed through strong surface cooling imposed on neutrally stratified wall-bounded ... -
Turbulence structures in isolated pool-riffle units
(University of Waterloo, 2019-01-28)The macroscale morphology of a river has significant effects on sediment transport, flow pattern, bed stability, and ecosystem function. Pools and riffles, which are respectively the deeper and shallower parts of the bed, ...
