DETERMINATION OF THE MIXING PERFORMANCE OF SULZER SMV STATIC MIXERS BY LASER-INDUCED FLUORESCENCE

Local concentrations are measured at the outlet of different configura tions of Sulzer SMV static mixers placed in a tube. Laser Induced Fluo rescence is the non intrusive technique used to measure mean and RMS c oncentrations. The two fluids mixed are miscible and the now regime is turbulent. The influence of the number of elements, their position an d the ratio between the velocities of the two compounds on the mixing is studied. The results show that these parameters are important for t he quality of mixing. The velocity ratio influences the radial mixing, while the mixing length depends on the number and position of the ele ments.
