• 20303 Dissolution Rate of Microbubbles in Turbulent Flow

抄録

This paper deals with the dissolution of microbubble in a turbulent round jet. We took detailed experimental data of velocity field and bubble radius by time-resolved optical measurements. The velocity field of gas-liquid flow was measured by Particle Imaging Velocimetry-Laser Induced Fluorescence (PIV-LIF). The bubble radius was measured by Interferometric Laser Imaging (ILI). Experimental data of dissolution rate were compared with a correlation equation derived by Sugiyama et al. (2004), in which shearing motions of turbulent small eddies are taken into account. The dissolution process in the experiment shows good agreement with that predicted by the correlation equation.
