Abstract
En 中文
Recent experiments have shown that tuning the initial wetting state of a hydrophobic surface before boiling gives rise to bubble behavior resembling that on hydrophilic surfaces. This contrasts with typical bubble behavior on hydrophobic surfaces, where bubble growth initiates from a residual vapor seed and results in slow growth and delayed departure. Here, we hypothesize that such wetting-state tuning modifies the near-surface liquid-vapor interfacial structure beneath the bubble, possibly through the formation of a near-surface thin liquid film, thereby altering bubble dynamics on hydrophobic surfaces.
