Abstract

A multiscale experimental procedure is introduced permitting the investigation of a special area of interest simultaneously to the global view of a 0.91x1x0.5m bubble column. The area of interest is acquired at a higher time and spatial resolution to achieve more accurate measures of the turbulent parameters. Discrimination of the global view and the magnifica-tion area is realised by the use of two lasers, emitting different wavelengths, and correspond-ing optical filters in front of the dedicated cameras. Since the two phase flow would introduce problematic conditions for the PIV algorithms a masking scheme for separating both phases is illustrated.
