Do we understand the flickering flames?

A research team at Toyohashi University of Technology discovered that the flickering of flames can be controlled by moving two flames closer together or further apart. By periodically adjusting the distance between flames, they were able to stably express the state of “stopping the flickering of flames”, a phenomenon previously unknown...
