Combustion engines can develop high frequency oscillations, leading to structural damage to and unsafe operating conditions. In Physics of Fluids, research clarifies the feedback processes that give rise to these oscillations. The investigators studied simulated combustion events in a computational model of a rocket combustor and their analysis involved sophisticated techniques, including symbolic dynamics and the use of complex networks to understand the transition into oscillatory behavior.
In a decade-long quest, scientists at Berkeley Lab, the University of Hawaii, and Florida International University uncover new clues to the origins of the universe – and land new chemistry for cleaner combustion engines
Argonne senior chemist Robert Tranter, a shockwave chemist, was named a fellow of the Combustion Institute.
David Blunck, an associate professor of mechanical engineering Oregon State University, is an expert on the burning of live fuels, such as live trees and bushes. Blunck and his colleagues use a combination of lab work, modeling, and field studies…
Bacteria that can help defuse highly toxic dioxin in sediments in the Passaic River – a Superfund hazardous waste site – could eventually aid cleanup efforts at other dioxin-contaminated sites around the world, according to Rutgers scientists. Their research, published in the journal Environmental Science & Technology, needs further work to realize the full potential of the beneficial bottom-dwelling microbes.
