Electric field effects flames (Electric-Field Effects on Laminar Diffusion Flames)
November 15, 2018 by
This gif image particularly demonstrates a methane flame under the influence of electric field. The electrical aspects of hydrocarbon flames contains amazing but complex nature that the flame geometry would be altered and experiencing this huge change. These images are first presented in May 2013 US National Meeting at Utah. The full set of image is published in “Electric Field Induced Changes of Diffusion Flame and Heat Transfer near an Impinging Surface” (Energies – MDPI).

UC Irvine — an article from School of Engineering

Electric-Field Effects on Laminar Diffusion Flames (E-FIELD Flames) – An UC Irvine article
“The problem is, it is difficult on Earth to try to understand how combustion works, because gravity and the resulting buoyancy affect the way flames behave. So scientists look to zero-gravity or microgravity environments to get an unadulterated view of the process.”
“NASA scientists and NASA contractors are critical to the operation as modifications and unplanned outcomes are the norm in zero-gravity science. Compromise is a constant companion. ‘We had to plan and calculate everything … it’s a little bit of a struggle,’ Chien says. “And sometimes things fail. Everything is not nice and smooth all the time.'”
“Are the results of Phase I what Dunn-Rankin and Chien expected? No. ‘We were expecting to see what we might see on Earth,’ says Chien, who ran similar experiments on terra firma during her doctoral studies at UCI. “But from the Space Station, we actually are seeing soot eliminated in some cases under the influences of the electric field.”

Soot accumulating on the fuel tube: Electric-Field Effects on Laminar Diffusion Flames( E-FIELD Flames)
June 15, 2018 by
Soot accumulates around the extruded fuel tube from the E-FIELD Flames experiment. This image overlaps two images — one before and after accumulation so the amount of the soot aggregates around the fuel tube can be easily and clearly observed.
