Summary: Boiling-induced vibration characteristics and mechanisms were investigated in pool boiling experiments. Turbulence and bubble collapse were identified as the two main mechanisms causing vibration. The peak amplitude of the first natural frequency increased with increasing heat flux and decreasing subcooling degree for turbulence-induced vibration. The peak amplitude of the second natural frequency increased with increasing heat flux for a certain subcooled temperature above 10 degrees C, and remained stable for lower subcooled temperatures. The dominant mechanism transitioned from bubble collapse to turbulence with decreasing subcooled temperature for a certain heat flux. The highest root-mean-square (RMS) value of vibration velocity corresponded to an increasing subcooled temperature with increasing heat flux.
