Numerical Simulation of Nonlinear and Dispersive Wave Equations using Adaptive Mesh Refinement (AMR)
(University of Waterloo, 2020-06-24)Numerical solution of time dependent Partial Differential Equations plays an important role in different fluid flow modelling problems. Sometimes a little portion of the computational domain needs high grid resolution in ... -
Numerical Simulation of Road Salt Impact at the Greenbrook Well Field, Kitchener, Ontario
(University of Waterloo, 2002)Chloride concentrations at the Greenbrook well field in Kitchener, Ontario, have been steadily increasing over the past several decades and may soon pose a threat to drinking water quality. Drinking water limits at some ... -
Numerical Simulation of Surface Waves using Meshfree Methods
(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 ... -
Numerical simulations of convection and gravity currents near the temperature of maximum density
(University of Waterloo, 2022-08-09)Recently, the dynamics of flows in cold freshwater (temperatures around the temperature of maximum density, 3.98 oC) has garnered much interest in the environmental fluid dynamics community. From a dynamical perspective, ... -
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 ... -
Numerical Simulations of Reactive Extrusion in Twin Screw Extruders
(University of Waterloo, 2010-01-18)In this work, the peroxide-initiated degradation of polypropylene (PP) in co-rotating intermeshing twin-screw extruders (COITSEs) is analyzed by means of numerical simulations. This reactive extrusion (REX) operation is ... -
Numerical Simulations of Shoaling Internal Solitary Waves of Elevation
(University of Waterloo, 2015-04-13)We present high-resolution, two- and three-dimensional direct numerical simulations of laboratory-scale, fully nonlinear internal solitary waves of elevation shoaling onto and over a small-amplitude shelf. The three-dimensional, ... -
Numerical Simulations of Small-scale and Full-scale Fire Experiments
(University of Waterloo, 2018-06-15)A fundamental part of fire safety engineering is dedicated to the application of numerical fire models. Accurate predictions of real-life fires are needed in scenarios related to fire growth, smoke propagation, occupant ... -
Numerical Simulations of Undrained Granular Media
(University of Waterloo, 2004)The objective of the present study was to develop a fluid flow-coupled distinct element model capable of capturing the undrained behaviour of granular soils by considering fundamental physical mechanisms that involve fluid ... -
Numerical Solutions of Two-factor Hamilton-Jacobi-Bellman Equations in Finance
(University of Waterloo, 2015-12-03)In this thesis, we focus on solving multidimensional HJB equations which are derived from optimal stochastic control problems in the financial market. We develop a fully implicit, unconditionally monotone finite difference ... -
Numerical Solutions to Stochastic Control Problems: When Monte Carlo Simulation Meets Nonparametric Regression
