Simulated combustion

I think it just looks cool but technically it’s a “direct numerical simulation of a lifted autoigniting ethylene-air jet flame… volume rendering of formaldehyde (blue/green) and hydroxyl radical (red/white) denoting the location of preignition upstream of flame and lifted flame, respectively.”

Found while browsing the NCCS site while researching the fastest computers in the world which this simulation was run on, Jaguar. It’s no wonder my engineering simulations take so long and look so less impressive.
