Abstract

A gas column in a tube with a temperature gradient spontaneously begins to oscillate when it is driven away from equilibrium. We observed a transition from the standing- to the traveling-acoustic-wave modes through a quasiperiodic state using a looped tube attached to a resonator. Through the measurements of entropy flow, we experimentally propose a thermodynamical mode selection rule, which acts as a guiding principle for a sequence of unstable modes appearing in nonequilibrium systems.
