The Global Consumption Speeds of Premixed Large-Hydrocarbon Fuel/Air Turbulent Bunsen Flame

In 2014 the United States consumed 18.49 million barrels of oil a day, 70 percent of which was used in transportation. Reducing this dependence on fossil fuel technologies is critical to the nation's security, economic stability, and environmental stewardship. Oil is a politically volatile, increasingly scarce resource that releases greenhouse gases when combusted and, as a result, is not sustainable at its current rate of consumption.

Reactions in internal combustion and gas turbine engines operate at elevated temperatures and pressures, and are primarily driven by turbulent premixed and partially premixed combustion of hydrocarbon fuels. Current estimates suggest there is nearly one passenger car per individual living in the United States. This statistic excludes delivery, public transit, and emergency vehicles as well as air and water transport vehicles. These vehicles use large-hydrocarbon liquid fuels such as gasoline, diesel, and jet fuel and will for the foreseeable future.

The turbulent flame speed is the rate at which a flame front propagates in an unburned turbulent fuel-air mixture. This measure is important to the fidelity of combustion models used in engine design and provides a means of directly analyzing and comparing fuels. However, turbulent flame speeds for most large-hydrocarbon fuels are not known. Thus, an accurate understanding of turbulent flame speeds is required to help overcome current challenges present in engine design.

An improved understanding of the turbulent combustion of large-hydrocarbon fuels used in transportation technologies is currently needed. This is motivated by the significance of the turbulent flame speeds in evaluating combustion models, and the ubiquity of large-hydrocarbon fuels. In my thesis I investigate the effects of local turbulent fluctuation on global combustion phenomenon such as the turbulent flame speed for these large-hydrocarbon fuels.

Lib lab

Video Series

LIB LAB, short for Library Laboratory, is a fun, educational video series Created, writen, Directed, and Hosted by AJ Fillo. The show started as a partnership with the Corvallis-Benton County Public Library and has grown into its own organization. Each episode explores a variety of scientific fundamentals with playful experiments and demonstrations. The videos live online, enabling audiences from around the world to participate in the experiments.

Experiments

Each video will also include directions for a related experiment, designed by AJ, that young viewers can conduct at home. Residents of Benton County can stop by the Youth reference desk at the Corvallis branch to pick up experiment materials, while supplies last!

Sorry, this part of aaronfillo.github.io is still under construction. I am working hard to get more content up and further expand my STEAM outreach efforts. Check back again later and thanks for stopping by.

Project x

Mission

Founded by AJ Fillo and Kyle Zada Project X is dedicated to connecting Oregon State University faculty interested in sponsoring outreach in Science, Technology, Engineering, Arts, and Mathematics (STEAM) fields with Oregon State University graduate and undergraduate students dedicated to completing STEAM outreach activities. All outreach activates undertaken by Project X will focus on providing both students and educators the tools necessary to enable student success in STEAM fields.

Who Can Get involved? Project X is open to all Oregon State University undergraduate and graduate students; we welcome all majors. Our mission goals require a wide range of skills from many different areas, such as engineering, graphic design, video editing, writing, teaching, performing, etc. We very much work off the adage, “The more the merrier.” You can't spell STEAM without TEAM.
