Glad to be granted a patent on prediction & control of blowout in combustion systems by @patentoffice.bsky.social. Our invention predicts the exact blowout time significantly earlier using a log periodic power law & performs control action to prevent the blowout.

We discover that by variation of an additional parameter, a complex system undergoes a change from continuous to abrupt transition, involving an intricate metamorphosis of transition (published in @apsphysics.bsky.social).

Our new work by phoenix02.bsky.social‬ in JFM @universitypress.cambridge.org reveals a 52° phase lag between vortex shedding and maximum vortical interaction in turbulent combustors. Disrupting these interactions can suppress thermoacoustic instability.
