Blue whirl flame structure

Caption

Blue whirls are a swirling flame phenomenon that evolves from a chaotic fire whirl and burns with nearly soot-free combustion. Supercomputer simulations have revealed the flame structure and flow structure of the blue whirl. (A) Volume rendering of the heat release rate from the numerical simulations. (B) Schematic diagram that summarizes a final result of the blue whirl simulation showing the combination of three different kinds of flame. (C) Observed blue whirl.
