Flow Generated by an Aerated Rushton Impeller: Two-phase PIV Experiments and Numerical Simulations

Experiments Most publications of velocity measurements in stirred tanks concern measurements in single-phase flows. An excellent review of these studies was made by Ranade and Joshi (1990a). Literature concerning velocity measurements in aerated stirred tanks is scarcer however. An overview of literature is given in Table 1. Lu and Ju (1987) used constant temperature anemometry (CTA) in order to determine liquid velocity profiles in an aerated stirred tank. However, laser Doppler anemometry (LDA) measurements have been used in most recent experiments. Two examples are the work of Morud and Hjertager (1996) and Roučar and Van den Akker (1994), who used laser Doppler anemometry (LDA) for the measurement of gas velocities in a stirred tank. Sharp et al. (1998) used PIV to measure the liquid velocity in a stirred tank. The time-averaged velocity fields show the classical jet flow and the
