Flow analysis by pulsed ultrasonic velocimetry technique in Sulzer SMX static mixer

An experimental investigation, by pulsed ultrasonic velocimetry technique has been conducted for flow analysis in Sulzer SMX static mixers in the transitional and turbulent flow regimes (1030 < Re < 13,270). Axial velocity profiles and turbulent intensity have been analyzed upstream, downstream and within the static mixer. Turbulence intensity is tracked as function of Reynolds number. In addition velocity and turbulent intensity profiles have been examined for eight circumferential probe positions downstream the SMX at Z = 0.7D. A circumferential dependence is observed and affects all the hydrodynamic parameters studied.
