Abstract
Light scattering characteristics of a spheroidal bubble are researched for turbulent bubbly flow in which bubbles are not exactly spheral. Aiming at the influence of shape of the bubble, the angular distributions of light scattered by prolate and oblate spheroidal bubbles with incident beam parallel to the rotating axis are calculated based on ray tracing method, neglecting the diffraction and interference. The width of incident beam is presented as a influencing factor for the light scattering. Furthermore, effects on the scattering properties are analyzed in terms of the shape parameter, refractive index of water and times of internal reflections and refractions. The results that the nonsphericity of bubbles has a considerable effect on their scattering profiles, can be used to optimize the bubbly flow measurements.
