Despite federal, state, and local efforts to combat environmental injustices resulting from heavy industrial activity and high air pollution levels, there is a widespread tendency for hazardous industrial activities to locate near low-income, underrepresented ethnic populations in the United States. The Houston Ship Channel, a port containing the largest concentration of Petrochemical Facilities in the United States, evidences this tendency and provides a stellar example of the nexus between pov...

Numerical modeling of shallow microtidal semi-enclosed estuaries requires the effective simulation of physical processes with a wide range of temporal and spatial scales. In theory, application of sufficient grid resolution in both the horizontal and vertical should result in a reasonable simulation. However, in practice, this is not the case. Fully resolving the finest scales can be computationally prohibitive, and various algorithmic assumptions can break down at fine resolutions, leading to s...

The General Purpose Frigate was the centrepiece of the Royal Canadian Navy’s fleet planning for over three years, and its cancellation by the newly elected Liberal government in October 1963 set off a divisive and chaotic yearlong debate over what should be built in its place. After exploring numerous options, such as aircraft carriers and nuclear submarines, the navy came to the conclusion that its best option was to pursue a guided missile destroyer program that was similar to the General Pur...

This thesis computationally analyzes the effect of commonly occurring ship load variations and wave induced bending moments on hull girder flexure. The deflection of the hull is used to determine the impact on the alignment of the vessel's combat system. Simple beam theory is applied for the structural portion of the analysis. Wave induced bending moments are determined by using a quasi-static approach with regular waves. Calculations and results are presented for theFFG7 calss of U.S. Navy frig...

The performance of an extended Kalman filter used to track a maneuvering surface target using HFDF lines-of-bearing is substantially improved by implementing a fixed interval smoothing algorithm and a maneuver detection method that uses a noise variance estimator process. This tracking routine is designed and implemented in a computer program developed for this thesis. The Hall noise model is used to accurately evaluate the performance of the tracking algorithm in a noisy environment. Several tr...

This is an analysis of existing feedback in the Fleet Modernization Program (FMP) planning and design process using the FFG-7 class of ships as a case study. This analysis attempts to relate the engineering drawing revision rate (inverse measure of drawing quality) and the number of ships affected by those drawing revisions (measure of availability concurrence) to the cost growth attributable to the FMP portion of U.S. Navy ship availabilities. Due to the lack of actual cost data, budget estimat...

A difficult problem in remote sensing is the detection of ships on the open ocean. For almost two decades, experimental spaceborne and airborne Synthetic Aperture Radars (SAR) have been used to image ships. However, SAR is inherently limited in (automated) ship detection because it relies on a single parameter, the radar Backscatter, to distinguish faint, small ship signatures from background. Along-Track Interferometry, a recently developed technique that uses two time displaced SAR images ...

The maximal frictional two-layer exchange flows in general and the exchange of water through the Burlington Ship Canal in particular were studied through both theoretical analysis and laboratory experiments. Gravitational two-way exchange flows are often driven by a slight density difference due to temperature, salinity and/or sediment concentration variations across a constriction connecting two water bodies. The exchange of two fluids of differing density through the constriction such as a cha...

Bahia Grande is a large lagoon located within Laguna Atascosa National Wildlife Refuge in Cameron County, Texas. When the Brownsville Ship Channel was built along the southern end of the lagoon in 1936, Bahia Grande was cut off from the marine water of Laguna Madre. Since that time, Bahia Grande has been primarily dry with only ephemeral fresh water coming from heavy rainfall events, resulting in a severe decline in biological productivity. A restoration project led by the U.S. Fish and Wildlife...

A high fidelity computational fluid dynamics approach to perform direct simulations of ship maneuvers is presented in this thesis. The approach uses dynamic overset grids with a hierarchy of bodies to enable arbitrary motions between objects, and overcome the difficulties in simulation of the moving rudder and rotating propeller. To better resolve propeller/rudder interaction a Delayed Detached Eddy Simulation turbulence model based on Menter’s SST is used. The methodology was implemented in the...

A computational fluid dynamics (CFD) methodology is presented to predict density stratified flows in the near-field of ships and submarines. The density is solved using a higher-order transport equation coupled with mass and momentum conservation. Turbulence is implemented with a k-ε/k-ω based Delayed Detached Eddy Simulation (DDES) approach, enabling explicit solution of larger energy-containing vortices in the wake. Validation tests are performed for a two-dimensional square cavity and the thr...

This thesis presents two important contributions to the modeling of entrainment of air bubbles in water, with focus on ship hydrodynamics applications. The first contribution consists of a general framework for modeling turbulent air entrainment. The framework attempts to describe the evolution of bubbles from their formation at the free surface, size distribution changes due to breakup and coalescence, and rise due to buoyancy. This proposed framework describes the complex entrainment process a...

The effects of winds and/or waves on ship motions, forces, moments, maneuverability and controllability are investigated with URANS computations. The air/water flow computations employ a semi-coupled approach in which water is not affected by air, but air is computed assuming the free surface as a moving immersed boundary. The exact potential solution of waves/wind problem is modified introducing a logarithmic blending in air, and imposed as boundary and initial conditions. The turbulent air flo...
