Ignition of bluff-body methane flames
(2009-05-21)
The movies show the ignition process following a spark in a bluff-body stabilised methane non-premixed flame. The flow is described in: S.F. Ahmed, R. Balachandran, T. Marchione, E. Mastorakos, Spark ignition of turbulent ...
Ignition of spray flame with multiple spark
(2009-05-25)
The movies have been taken at 4000 fps. The spark is placed at a distance z from the nozzle and at 5mm from the enclosure. The ignition unit delivers at 100Hz a spark lasting 8ms, followed by 2ms of no activity. The front ...
Flame in methane jet after spark ignition
(2009-05-21)
The video shows the flame motion following spark ignition in a turbulent methane jet. The flow conditions were: 30% air, 70% CH4, jet velocity 12.5m/s & 25m/s, framing rate 4200 fps, spark at r=0, z=40d (40 jet diameters; ...
Autoignition of a H2 jet in hot air flow
(2009-05-21)
The movie (taken with a conventional video camera at 30fps) shows the various operation modes of the Cambridge Autoignition experiment, described in: C.N. Markides, E. Mastorakos,
An experimental study of hydrogen ...
Direct numerical simulations of spray spark ignition
(Engineering Department, 2010-09-09)
Direct Numerical Simulations (DNS) of a mono-disperse spray in a turbulent flow have been used to explore the nature of flame kernels when a spark is deposited in the spray. The simulations use complicated chemistry and ...
Autoignition of droplets in hot air flow
(2010-09-09)
A single-droplet generator has been used to inject fuel droplets of various sizes and chemical composition into a hot turbulent air flow. The ensuing autoignition and flame behaviour has been recorded with a fast camera. ...
