  • Experimental investigation of the impact of surface tension and artificial nucleation site geometry on the bubble growth [Elektronski vir]
    Vodopivec, Matevž, strojnik ...
    The present work provides an experimental assessment of the impact of liquid surface tension on the single bubble dynamics generated by artificial nucleation cavities during boiling in a quiescent ... liquid. De-ionized water is used with and without added non-ionic surfactant (Dynol 800) to modify the fluid's surface tension while keeping the other thermo-physical fluid properties unchanged. Furthermore, two different cavity geometries are investigated: a vertical and a 30°-inclined cone produced via femtosecond laser texturing. This paper shows preliminary results related to the influence of surface tension and cavity geometry on the single bubble dynamics. A methodological baseline is provided to enable future studies aiming to answer still-open questions about vapour bubble nucleation phenomena.
