Controlling Steam Flood Migration With Air Injection Wells, Rex Hodges

All Dissertations

Steam flooding is an aggressive remediation technology for removing volatile organic chemical (VOC) sources that slowly dissolve into passing groundwater. Plume concentrations can be reduced, accelerating cleanup, and decreasing plume management costs. Steam injected in wells surrounding the source spreads outward and develops into a front that drives contamination to a system of groundwater pumping wells in the saturated zone and soil vapor extraction wells in the vadose zone. The process can be modeled with the non-isothermal multi-phase flow simulator T2VOC to include operation designs and factors at individual sites.

Analysis Of Hat Sectioned Reinforced Composite Beams Including Thermal Effects, Kashif Ali Nayyer Syed

Civil Engineering Dissertations - Archive

A simple analytical method for analyzing fiber reinforced polymeric composite beams with hat cross-section is presented. The method includes development of closed-form expression of the axial, bending and their coupling stiffness matrices for the composite beams. The stiffness matrices are obtained by transforming the actual geometrical cross-section of the beam into an equivalent plate using transformation matrices and Parallel Axis theorem. Ply stresses due to mechanical as well as thermal load can easily be obtained at any given location of the beam section. In this approach, the effect of induced in-plane deformation due to bending for an unsymmetrical cross-section is …

Computer Model To Select Leed Certification For Building Projects, Ruba Mirghani Mohammed

Masters Theses

According to the US Green Building Council (USGBC) residential and commercial buildings in the United State consume huge amounts of natural resources; pollute the environment, and generate large amounts of waste, all of which affect the environment, economy, public health, and productivity. As a result, USGBC committees developed the Leadership in Energy and Environmental Design (LEED) rating system to help professionals improve the quality of buildings and lessen their impact on the environment.

Civil and Environmental Engineering Faculty Research Publications

A reliability-based optimization (RBO) procedure is developed and applied to minimize the weight of eight fiber-reinforced polymer composite bridge deck panel configurations. The method utilizes interlinked finite element, optimization, and reliability analysis procedures to solve the weight minimization problem with a deterministic strength constraint and two probabilistic deflection constraints. Panels are composed of an upper face plate, lower face plate, and a grid of interior stiffeners. Different panel depths and stiffener layouts are considered. Sensitivity analyses are conducted to identify significant design and random variables.

JTRP Technical Reports

This report focuses on the evaluation of the factors affecting cone resistance measurement during cone penetration in saturated clayey soils and the application of the result to pile shaft capacity analysis. In particular, effects of drainage conditions around the cone tip were studied. Rate effects related to both drainage and shear strength dependence on loading rate were studied. In order to investigate the effects of drainage during penetration, penetration tests were performed with various velocities in the field and in a calibration chamber, and the obtained data were analyzed. For the field tests, two sites which have homogeneous clayey soil …

Information Infrastructure For Integrated Ecohydraulic And Water Resources Modeling And Assessment, R. Wallace, K. Pathak, M. Fife, Norman L. Jones, J. P. Holland, D. Stuart, J. Harris, C. Butler, D. R. Richards

Faculty Publications

Watershed management increasingly requires ecohydraulic modeling and assessment within a regional context, rather than on a project-by-project basis. Such holistic modeling and assessment require evaluation capabilities across multiple temporal and spatial scales. Thus, modeling and assessment tools must be integrated in a scientifically and computationally effective infrastructure. The US Army Engineer Research and Development Center, in concert with the Hydrologic Engineering Center and its academic partners, including Brigham Young University, is establishing a comprehensive set of hydroinformatics modeling and assessment tools for ecohydraulic and water resources management applications, all linked based on a common data and information infrastructure. This paper …

Influence Of Arctic Wetlands On Arctic Atmospheric Circulation, William J. Gutowski Jr., Helen Wei, Charles J. Vörösmarty, Balazs M. Fekete

Advanced Science Research Center

The Arctic’s land surface has large areas of wetlands that exchange moisture, energy, and momentum with the atmosphere. The authors use a mesoscale, pan-Arctic model simulating the summer of 1986 to examine links between the wetlands and arctic atmospheric dynamics and water cycling. Simulations with and without wetlands are compared to simulations using perturbed initial and lateral boundary conditions to delineate when and where the wetlands influence rises above nonlinear internal variability. The perturbation runs expose the temporal variability of the circulation’s sensitivity to changes in lower boundary conditions. For the wetlands cases examined here, the period of the most …

A New Spectroscopic Method For The Non-Destructive Characterization Of Weathering Damage In Plastics, Andrew Robert George

Theses and Dissertations

The weathering of plastics and composites is a problem because of the loss of both physical and mechanical properties that it causes in these materials. But this weathering effect has been difficult, and in some cases, impossible to characterize without the destruction of the plastic or composite part. Clearly a rapid, reliable, and non-destructive test for the extent of the weathering damage is critically needed. A recent problem that arose at Superyacht Solutions, a boat repair company in Australia, required a solution to just this problem. Such a test was developed for Superyacht Solutions, and is being applied across a …
