Assessing Public Health Burden Associated With Exposure To Ambient Black Carbon In The United States, Ying Li, Daven K. Henze, Darby Jack, Barron H. Henderson, Patrick L. Kinney

Ying Li

Black carbon (BC) is a significant component of fine particulate matter (PM2.5) air pollution, which has been linked to a series of adverse health effects, in particular premature mortality. Recent scientific research indicates that BC also plays an important role in climate change. Therefore, controlling black carbon emissions provides an opportunity for a double dividend. This study quantifies the national burden of mortality and morbidity attributable to exposure to ambient BC in the United States (US). We use GEOS–Chem, a global 3-D model of atmospheric composition to estimate the 2010 annual average BC levels at 0.5 x 0.667° resolution, and …

High Speed Flight At Low Altitude: Hazard To Commercial Aviation ?, Paul F. Eschenfelder , Capt. Mar 2011

High Speed Flight At Low Altitude: Hazard To Commercial Aviation ?, Paul F. Eschenfelder , Capt.

Paul F. Eschenfelder

Commercial aircraft are capable of, and in fact, do, operate at high speed (>250 knots indicated airspeed [KIAS]) at low altitude (below 10,000’ above ground level) worldwide. Design, construction and certification standards for these aircraft were developed over 40 years ago. Since the development of these standards populations of large flocking birds have increased dramatically in many parts of the world. Yet neither design/construction standards nor operational practice have changed to reflect the new threat. Subsequent serious damage resulting from recent collisions indicates change is necessary. Since 2003, flight rules in Canada and the United States have been amended, …

The uncertainty analysis is performed using a newly developed point estimate method, …


New Observations Of Gas-Phase Expansion Above A Dense Non-Aqueous Phase Liquid Pool, Kevin G. Mumford, James E. Smith, Sarah E. Dickson May 2009

New Observations Of Gas-Phase Expansion Above A Dense Non-Aqueous Phase Liquid Pool, Kevin G. Mumford, James E. Smith, Sarah E. Dickson

Sarah E Dickson

The partitioning of volatile dense nonaqueous phase liquid (DNAPL) compounds to a discontinuous gas phase results in the repeated expansion, fragmentation, and vertical mobilization of gas clusters. This process has the potential to significantly affect the dissolution of DNAPL source zones and the characterization of DNAPL-contaminated sites, but has not been included in common conceptual models. This study presents new observations of discontinuous gas-phase growth above a 1,1,1-trichloroethane pool in a two-dimensional flow cell packed with 1.1-mm diameter sand. In contrast to the behavior observed in coarse glass beads, these visualization results show that the gas phase evolves as a …


Influence Of Aperture Field Heterogeneity And Anisotropy On Dispersion Regimes And Dispersivity In Single Fractures, Qinghuai Zheng, Sarah E. Dickson, Yiping Guo Jan 2009

Influence Of Aperture Field Heterogeneity And Anisotropy On Dispersion Regimes And Dispersivity In Single Fractures, Qinghuai Zheng, Sarah E. Dickson, Yiping Guo

Sarah E Dickson

A 33 factorial experimental design was implemented to numerically investigate the interactive effect of the mean (μ b ), standard deviation (σ b ), and anisotropic ratio (AR) (λ b x /λ b y ) of single-fracture apertures on dispersion regimes (specifically Taylor dispersion and geometric dispersion) and dispersivity. The Reynolds equation was solved to obtain the flow fields in each computer-generated fracture, and the random walk particle tracking method was used to simulate solute transport. The simulation results show that (1) for a fixed hydraulic gradient, the dominant dispersion regime is controlled by μ b , and to a …


Differential Transport And Dispersion Of Colloids Relative To Solutes In Single Fractures, Qinghuai Zheng, Sarah E. Dickson, Yiping Guo Jan 2009

Differential Transport And Dispersion Of Colloids Relative To Solutes In Single Fractures, Qinghuai Zheng, Sarah E. Dickson, Yiping Guo

Sarah E Dickson

This work employed numerical experiments simulating colloid and solute transport in single parallelplate fractures, using the random walk particle tracking method, to demonstrate that (1) there exists an aspect ratio of the colloid radius to half the fracture aperture, do, where the average velocities of colloids and solutes are similar. When d > do, the velocity distribution assumption is satisfied, and the fact that the ratio of the colloid transport velocity to the solute transport velocity, sp, decreases as d increases is well documented in the literature. However, when d < do, the velocity distribution assumption is violated, and sp increases as d increases and (2) the Taylor dispersion coefficient and its extension by James and Chrysikopoulos [S.C. James, C. V. Chrysikopoulos, J. Colloid Interface Sci. 263 (2003) 288] will overestimate the colloid dispersion coefficient significantly. Additionally, numerical experiments simulating colloid and solute transport in variable-aperture fractures demonstrated that sp and DL,coll /DL,solute decrease with increasing CoV, and the anisotropy ratio only plays a minor role compared to the CoV. These observations have important implications towards the interpretation of colloid transport in both porous and fractured media.
