Combined simultaneous two-phase PIV and interface elevation measurements in stratified gas/liquid pipe flow

摘要

The multiphase flow loop at the University of Oslo has been upgraded with a wave measurement gauge consisting of two conductance probes. Hence, we are able to combine the simultaneous two-phase Ply (S2P-PIV) technique, which was presented in a previous paper, and wave field measurements. This unique combination allows us to investigate the flow dynamics of both phases, e.g. velocity profiles, turbulence profiles, distribution of turbulent structures, as well as the wave statistics, e.g. wave amplitudes and speeds, power spectral densities, of the exact same stratified flow pattern.
