Modeling The Release And Spreading Of Permanganate From Aerated Slow-Release Oxidants In A Laboratory Flow Tank, Ann Kambhu, Yusong Li, Troy E. Gilmore, Steve D. Comfort

School of Natural Resources: Faculty Publications

Aerated, slow-release oxidants are a relatively new technology for treating contaminated aquifers. A critical need for advancing this technology is developing a reliable method for predicting the radius of influence (ROI) around each drive point. In this work, we report a series of laboratory flow tank experiments and numerical modeling efforts designed to predict the release and spreading of permanganate from aerated oxidant candles (oxidant-wax composites). To mimic the design of the oxidant delivery system used in the field, a double screen was used in a series of flow tank experiments where the oxidant was placed inside the inner screen …

Improving Vertical Axis Wind Turbine (Vawt) Performance With Placement Strategies: Final Report, Patrick A. Tebbe, Nazli A. Yilmaz Wodzinski, Namyong Lee

Mechanical and Civil Engineering Department Publications

This project was focused on the use and placement of vertical axis wind turbines (VAWTs). Studies were focused on areas not typically addressed in previous work; small wind at very low elevations (i.e. within the boundary layer). Numerical studies were made of how VAWTs function as well as the potential wind environments they may be placed in. A simplified numerical code, based on two-dimensional potential flow functions, was developed to model flow around buildings and other structures. The code allows a rapid determination of regions where flow may experience speed-up and where turbulence may result.

Experimental facilities were designed and …

Defect Detection In Freight Railcar Tapered-Roller Bearings Using Vibration Techniques, Constantine Tarawneh, Joseph Montalvo, Brent Wilson

Mechanical Engineering Faculty Publications

Currently, there are two types of defect detection systems used to monitor the health of freight railcar bearings in service: wayside hot-box detection systems and trackside acoustic detection systems. These systems have proven to be inefficient in accurately determining bearing health, especially in the early stages of defect development. To that end, a prototype onboard bearing condition monitoring system has been developed and validated through extensive laboratory testing and a designated field test in 2015 at the Transportation Technology Center, Inc. in Pueblo, CO. The devised system can accurately and reliably characterize the health of bearings based on developed vibration …

Transdermal Uptake Of Benzophenone-3 From Clothing: Comparison Of Human Participant Results To Model Predictions, Azin Eftekhari, Jonathan T. Hill, Glenn C. Morrison

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Background: Models of transdermal uptake of chemicals from clothing have been developed but not compared with recent human subject experiments. In a well-characterized experiment, participants wore t-shirts pre-dosed with benzophenone-3 (BP-3) and BP-3 and a metabolite were monitored in urine voids. Objective: Compare a dynamic model of transdermal uptake from clothing to results of the human subject experiment. Methods: The model simulating dynamic transdermal uptake from clothing was coupled with direct measurements of the gas phase concentration of benzophenone-3 (BP-3) near the surface of clothing to simulate the conditions of the human subject experiment. Results: The base-case model results were …

Investigating The Impacts Of Crash Prediction Models On Quantifying Safety Effectiveness Of Adaptive Signal Control Systems, Weimin Jin, Mashrur Chowdhury, Sakib Mahmud Khan, Patrick Gerard

Publications

Introduction: Adaptive Signal Control System (ASCS) can improve both operational and safety benefits at signalized corridors. Methods: This paper develops a series of models accounting for model forms and possible predictors and implements these models in Empirical Bayes (EB) and Fully Bayesian (FB) frameworks for ASCS safety evaluation studies. Different models are validated in terms of the ability to reduce the potential bias and variance of prediction and improve the safety effectiveness estimation accuracy using real-world crash data from non-ASCS sites. This paper then develops the safety effectiveness of ASCS at six different corridors with a total of 65 signalized …

Adaptive Signal System Safety Impacts Final Report, Mashrur Chowdhury, Weiman Jin, M. Sabbir Salek, Sakib Mahmud Khan, Katherine Brunk, Patrick Gerard, Nathan Huynh, Mohammad Torkjazi

Publications

The research team conducted a literature review and a nation-wide survey at the beginning of the research. The literature review revealed that Adaptive Signal Control System (ASCS) was effective in reducing crashes in some studies, while in other studies, the crash reduction due to ASCS was not statistically significant. Twenty-eight states participated in the nation-wide survey and helped the research team identify corridor characteristics, such as the design speed and Annual Average Daily Traffic (AADT) of an ASCS corridor, which would allow for the best operational and safety outcomes. Then, to determine the safety effects of ASCS, the research team …

A High-Temperature-Resistant Inorganic Matrix For Concrete Structures Enhanced By Fiber-Reinforced Polymer, Jing Zhu, Wenzhong Zheng, Lili Xie, Lesley Sneed

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

This paper probed deep into a high-temperature resistant inorganic matrix: alkali-activated slag cement (AASC), which is a kind of cementitious material prepared by alkali-activator and pozzolanic or latent hydraulic material. Firstly, the mix ratio of the AASC was optimized to improve the wettability and mechanical properties. Then, the effects of the adhesive matrix and the type of fiber-reinforced polymer (FRP) were observed through FRP-to-concrete bond tests on 93 specimens. The test results, coupled with anchorage analysis, indicate that the AASC has comparable reinforcing effects as those of organic epoxy matrix; the anchorage length of FRP sheets has a significant influence …

Evaluation Of Orange Pavement Striping For Use In Work Zones, Erin Lammers-Staats, William Staats, Ken Agent

Kentucky Transportation Center Research Report

Interstate widening projects are commonplace in Kentucky, and safety is of primary concern within the project work zone. Past experience with long work zones revealed two critical safety issues: driver confusion due to unclear pavement markings and a lack of continuous work zone signage for motorists indicating they are still within a work zone. This concern is heightened in transition and taper areas. Highly visible markings in an alternative color other than standard yellow or white might better distinguish the proper travel path for motorists and prevent drivers from returning to normal driving behavior and speeds once they get through …

Fiscal Year 2019 Fhwa-536 Report For The Kentucky Transportation Cabinet, Doug Kreis, Candice Wallace, Bryan Gibson, Sarah Mccormack

Kentucky Transportation Center Research Report

The Federal Highway Administration (FHWA) requires state transportation agencies to submit a biennial report on local highway finances. The purpose of these reports is to provide FHWA with the data it needs to capture the financing of highway activities at the local level. Based on this information, it can identify trends in revenue, expenditures, investments, and program development, and in turn make decisions about future investments. The report, FHWA-536, asks agencies to report on four areas of local highway finance: 1) disposition of highway-user revenues; 2) revenues used for roads and streets identified by source and funding type; 3) road …
