Characterization of the dissolved organic matter in steam assisted gravity drainage boiler blow-down water
DownloadFall 2012
The presence of high concentrations of dissolved organic matter (DOM) and total dissolved solids (TDS) in the boiler blow-down water (BBD) causes severe equipment fouling during the SAGD operation. For effective BBD management, a detailed understanding of the BBD chemistry is important. In this...

Colloidal Fouling of Salt Rejecting Nanofiltration Membranes: Transient Electrokinetic Model and Experimental Study
DownloadFall 2012
Membrane separation processes are widely used for separation of colloids, macromolecules, organic and ions. Among different processes, nanofiltration (NF) is being increasingly used for removing multiple molecular weight and size solutes using a single membrane. Fouling is a commonly encountered...

Fall 2012
To understand the water cycle on Mars, details of mass and energy transfer between the surface and the atmosphere are of importance. A complete model, involving transient variations of the water in gaseous and solid phases in the atmosphere and the regolith, is developed and solved numerically...

Data-Driven Fault Detection, Isolation and Identification of Rotating Machinery: with Applications to Pumps and Gearboxes
DownloadFall 2012
Fault diagnosis plays an important role in the reliable operation of rotating machinery. Data-driven approaches for fault diagnosis rely purely on historical data. Depending on how a diagnosis decision is made, this thesis divides data-driven fault diagnosis approaches into two groups:...

Design and Analysis of Complex Composite Structure Subjected to Combined Loading Conditions
DownloadFall 2012
Axisymmetric fiber-reinforced polymer composite structures such as pressure vessels and piping manufactured by braiding and filament winding are being widely used in different industrial applications where combined loading conditions may be applied. The aim of this study was to determine the...

Design and Use of Servo-Driven Actuators for Spanwise-Varying Control of a Backward-Facing Step Flow
DownloadSpring 2012
An experimental study was conducted of a forced backward-facing step water flow, and the design of 16 actuators for creating the perturbations used to force the flow. The 16 actuators allowed for variant forcing in the spanwise direction with a resolution of 0.5 times the step height h. They are...

Development of a Novel Electro-thermal Anti-icing System for Fiber-reinforced Polymer Composite Airfoils
DownloadFall 2012
Given the trend towards expanded use of polymeric composites for wind turbine blades and aircrafts wing, icing of polymer composite airfoils is a challenge; this thesis is addressing this issue from a conceptual perspective. For the first time, the concept of embedded thermal elements as an...

Development of an Experimental Apparatus for Studying the Effects of Acoustic Excitation on Viscosity
DownloadFall 2012
An experimental apparatus was developed capable of measuring changes in fluid viscosity occurring due to acoustic stimulation. Controls allowed measurements at simulated oil sand reservoir pressures and temperatures with near real-time data visualization. Calibration was performed...

Development of Empirical Models to Predict Deposition of Aerosols in the Extrathoracic Airways of Children
DownloadSpring 2012
The experimental studies described in this thesis were performed with the goal of measuring deposition of aerosols, inhaled either nasally or orally, in the extrathoracic airways of children in different age groups. We pursued in vitro methods and characterized the deposition of aerosols in the...
