Abstract [en]

The vibration responses and bubble behaviors are simultaneously measured when subcooled pool boiling occurs on a vertical heated surface. The vibration velocity of the heated surface is collected with a non-contact laser system while the bubble behaviors are captured by a high-speed camera. Experiments with different heat flux and subcooling are carried out, and the vibration responses correlated with the bubble behaviors are analyzed. The results show that with the increase of heat flux, more nucleation sites on the heated surface are activated, and bubble interactions occur. Four typical modes are extracted from the experimental data with isolated bubbles from a single site, continuous bubbles from a single site, bubbles from two sites and bubbles from multiple sites. The main excitation mechanism for all the cases is the pressure fluctuations caused by the rapid growth of the bubble at the initial stage, and other bubble behaviors such as departure, collapse and bubble interactions show insignificant influence. Moreover, the vibration responses in time and frequency domain are strongly related to the temperature distribution before bubble initiation and the position of the nucleation site for isolated boiling bubbles. The generation behaviors of the bubbles also affect the vibration responses especially in frequency domain.
