摘要：
The paper describes an experimental study of thermal fluctuations during transition from bubble to film boiling of water on a wire heater and fluctuations of the shape of a superheated liquid jet discharged from a high‐pressure vessel. It is found that for a heat‐transfer crisis on the wire heater and for intense volume boiling of the superheated liquid jet, the fluctuation power spectrum has a low‐frequency component (flicker noise) that diverges under the law 1/f. This effect is due to nonequilibrium phase transitions in the system: the heat‐transfer crisis during transition from bubble to film boiling and a flow crisis during boiling of the superheated liquid jet.
