Abstract

Vapor bubble nucleation during subcooled boiling on thin strip wire heaters and the resultant vibrations are studied experimentally. The results show how the subcooled boiling-induced vibrations (SBIV) are intrinsically related to the hydrodynamic flow induced near the heated wires. It is shown that the dominant force responsible for the vibrations in this case is imposed by a localized strong hydrodynamic flow rather than by the vapor recoil force. The dominant frequency of SBIV is the fundamental frequency of the wire, regardless of the individual departure frequencies of the nucleating vapor bubbles. The recorded wire vibrations are used to quantify the hydrodynamic flow. It is shown experimentally and theoretically that the flow fades exponentially with distance from the wire.
