Abstract

An experimental investigation of the Marangoni convection around a single vapor bubble ofFC-72 on a downward-facing heated surface was reported. The boiling cell used for thisstudy was equipped with an optical measurement system which was dedicated to the ParticleTracking Velocimetry (PTV) method. This method allowed us to obtain the velocity fields inthe liquid around the vapor bubble. From the velocity fields obtained, we verified thepresence of Marangoni convection rolls in the vicinity of the liquid-vapor interface.Lastly, the influence of levels of subcooling on the velocity of convective rolls relatedto the Marangoni effect was investigated.
