Three-Dimensional Numerical Investigation on Velocity Field and Mixing Characteristics at Channel Junctions
DownloadFall 2014
Channel confluence is an important component in river systems. The flow dynamics and mixing processes associated with such geometry are highly three-dimensional and complicated. In this study, a commercial software, ANSYS CFX, was employed to investigate the flow structures and mixing...

The Effects of Mixing, Reaction Rate and Stoichiometry on Yield for Mixing Sensitive Reactions
DownloadSpring 2010
Competitive-Consecutive and Competitive-Parallel reactions are both mixing sensitive reactions; the yield of desired product from these reactions depends on how fast the reactants are brought together. Recent experimental results have suggested that the mixing effect may depend strongly on the...

The impact of mixing on diluted bitumen de-watering is studied in two stages using a fractional factorial design of experiments. The first stage evaluates the relative effects of bulk demulsifier dosage, local maximum energy dissipation, and mixing time. The second stage of experiments evaluates...

Fluidized beds offer efficient solutions for segregation of clay and bitumen pellets in the oil production industry. However, the hydrodynamics of these systems is not well-known and they are mostly operated as ``black box''. The removal of clay pellets in the mechanical separation of oil sands...

Carbon isotope analyses of gases extracted from drilling muds while drilling in the Western Canada Sedimentary Basin (WCSB) can be used to create carbon isotopic depth profiles. These profiles provide essentially continuous data through the stratigraphic section, offering a unique opportunity to...

Bitumen froth is an intermediate product of bitumen upgrading which must be treated to remove solids and water. De-mineralization and de-watering occur through a settling operation in which the addition of a diluent and a demulsifier are crucial to its success. This work explores the effect of...

Fall 2013
The impact of mixing on water removal from diluted bitumen and bitumen froth is studied, with the goal of maximizing demulsifier performance. The relative effects of bulk concentration, mixing intensity, mixing time and injection concentration on the demulsifier performance are evaluated. A...

Measurement and Analysis of Changes in Drop Size Distribution during Bitumen Clarification using Image Analysis
DownloadFall 2013
The impact of mixing on demulsifier performance is studied using image analysis. Three experimental campaigns based on fractional factorial designs were performed in a CIST (Confined Impeller Stirred Tank), varying demulsifier bulk concentration (BC) and injection concentration (IC), mixing time...

The current work presents the results of an experimental study on the effects of submergence on the performance of a submerged hydraulic jump with baffle blocks downstream of a sluice gate. A wide range of Froude numbers, submergence factors, and block sizes, locations and arrangements were...
