Congratulations Ram and Joey on winning the CI Image Award Competition!

May 27, 2021 by Michael Gollner

Congratulations to Dr. Sriram Bharath Hariharan, postdoctoral scholar and Joseph Dowling, PhD candidate on their Combustion Art submission “Walls of Fire” which was selected for the Technical Merit Award in the 12th US National Combustion Meeting!

Walls of Fire

Fire whirls can form under a variety of different flow conditions. One common flow condition that results in their formation is the presence of multiple line fires, which cause buoyant plumes (walls) to surround a central pseudo enclosure. The low pressure in this region is conducive to the entrainment of swirling flow, resulting in the formation of a fire whirl. This image shows a laboratory study of this configuration, formed using a fuel pool 10 cm in diameter, surrounded by four line fires, all with n-heptane. This image was captured using a Nikon D500 at f/14 with an exposure time of 1/800 s.
The authors thank the Bureau of Safety and Environmental Enforcement (140E0121C0004) for supporting this work.

The large #wildfires in #Chile are spreading quickly across large areas of non-native plantations of radiata pine and eucalyptus, many of them planted by foreigners during a dictatorship. These maps show recent MODIS heat detections on top of mapping of plantations (purple). 1/x

Tragic wildfire situation in Chile.

Tragic wildfire situation in Chile.
TheHotshotWakeUp: Podcast@HotshotWake

Absolute chaos in Chile today. 7 people have been reported killed so far during this week’s fires. I am getting reports from helicopter pilots down there working, seeing whole villages run over while they try to operate. Unreal accounts coming out of the country #Chile #wildfire

Western wildfires destroyed 246% more homes and buildings over the past decade – fire scientists explain what's changing

More homes are burning in wildfires in nearly every Western state. The reason? Humans.
