What it is

Nathan Kutz presents the spatio-temporal dynamics of rotating detonation rocket engines, including combustion fronts that behave like solitons. He shows a bifurcation analysis of a multiscale model that captures the main features.

Why Hacker News recommends it

HN commenters recommend it for its fluid dynamics of detonation waves and its high-speed imaging of rotating pulses.
