Sponsored Research Projects, Dr. Melanie Sattler
"Assessing Control Strategies for Ground Level Ozone," funded by Texas Utilities Environmental Research Program, 2006-2008. TXU
Aftermarket Technology and Fuel Additive Research Program, funded by the North Central Texas Council of Governments, 2005-2007.
Project Goals: To evaluate retrofit devices and fuel additives that claim to reduce vehicle exhaust emissions.
Using Operations-Oriented Performance Measures to Support Freeway Management Systems funded by Texas Department of Transportation, 2005-2007.
Project Goals: To
create a process which can collect, store, and produce the information
necessary to enhance traffic management center decision making, based
on operational and emissions based strategies.
On-Road Measurement of Air Quality Benefits: Traffic Signal Improvements, funded by Texas Air Research Center, 2004-2005.
Project Goals: Measure the effectiveness of traffic signal improvements in reducing automobile emissions, using a vehicle on-board NOx emissions measurement system.
Control of Reduced Sulfide Compounds in Air using Adsorption and Biofiltration, funded by UTA Research Enhancement Program, 2003-2004.
Project Goals: Optimize removal of air-borne carbonyl sulfide, a hazardous air pollutant and odor-causing compound, via adsorption and biofiltration, by varying parameters such as relative humidity, type of adsorbent, and type of biofilter media.
Lab InformationThe Air Quality Lab contains 3 lab-scale air pollution control systems for testing: a biofilter system, an adsorption system, and a photocatalytic oxidation system. The lab also contains the following measurement/analytical equipment:
- SRI 8610C Gas Chromatograph with Flame Ionization Detector
- International Sensor Technology IQ-350 solid state sensor for measuring a variety of gases
- an analytic balance, pH meter, and relative humidity stick
UTA also owns a Horiba-1300 OBS (on-board measurement) system for measuring tailpipe emissions of NOx, HC, CO, and CO2. The 1300 logs second-by-second measurements of pollutant concentrations, along with tailpipe flow rate, temperature and pressure. Ambient temperature and pressure are measured, and the system includes a GPS unit that records second-by-second position data for determining vehicle velocity and acceleration.
