Wildfire in Edinburgh!

Yesterday (Sunday 14th March) there was a wildfire on Arthur's Seat - the hill that dominates the Edinburgh skyline. It didn't last long and was successfully controlled within about ten minutes. I was a couple of miles away and took a photo:

Visit of Prof Lyons and seminar on reacting flows

Prof Kevin Lyons from North Carolina State University, Department of Mechanical and Aerospace Engineering, is visiting us on Thurs 18 March and will give a seminar at 1.15pm  in the AGB Seminar Room in the 3rd floor. The title of the talk is "Studies of Turbulent Reacting Flows: Experiments".

Studies of Turbulent Reacting Flows: Experiments by KM Lyons.

Studies are presented that examine a variety of phenomena in jet flames, including current work in flame propagation, hysteresis and blowout.  At a certain jet exit velocity, a flame will lift from the fuel nozzle and stabilize at some downstream position.  The partially-premixed flame front of the lifted flame oscillates in the axial direction, with the oscillations becoming greater in flames stabilized further downstream.  These oscillations are also observed in flames where blowout is imminent.  This work attempts to determine the role of fuel velocity and air co-flow on flame oscillations in both stable and unstable regimes.  The results of video imaging of a lifted methane-air diffusion flame are presented.  Images are used to ascertain the changes in the reaction zone that influence these oscillations and relate the movement to blowout.  Similar studies are presented in studies of upstream flame propagation in jets flames.  If time allows, other work in flame hysteresis, flame hazards in explosions and firefighting situations and the like, will be discussed.
