Determination of the Mixing Rate of a High Velocity Feed Stream in Agitated Vessels

An experimental and CFD study of liquid jet injection into a partially baffled mixing vessel: A contribution to process safety by improving the quenching of runaway reactions

“…Although experiments are carried out with very low feed velocities, leading to laminar flow in the feed pipes, the studies of Baldyga et al (1993) or Bałdyga and Pohorecki (1995) discuss the processes of micro, meso and macromixing in the vessel where the flow is turbulent. Concerning high velocity feeds, Verschuren et al (2001) provided a method for the calculation of the time-scale of turbulent dispersion of the feed stream introduced inside a stirred vessel. Recently, Bhattacharya and Kresta (2006) used a mixing-sensitive chemical reaction to analyse the effects of the feed time and the jet velocity on the performance of a reactor fed with a high velocity surface jet.…”
