Fluid Mixing and the Safe Quenching of a Runaway Reaction in a Stirred Autoclave

CFD Simulations for Safety of Chemical Reactors and Storage Tanks

“…2 Details concerning the CFD model employed are shown in Tab. 4. The laminar CFD model was employed to model liquid flow caused by free convection.…”

“…These computational experiments conducted with the use of CFD models can be very useful, particularly for industrial processes, for which safety experiments carried out in real installations are expensive and usually very dangerous. Several contributions devoted to CFD applications to study runaway reactions can be found in the literature -amongst others, see papers by Kammel et al [3], Hristov et al [4], Dakshinamororthy et al [5], and Molga et al [6][7][8][9].…”

Theoretical Study of Palladium Membrane Reactor Performance During Propane Dehydrogenation Using CFD Method

“…There are few works [4][5][6][7][8][9][10][11][12][13][14][15][16] devoted to mathematical modeling of various processes in the Pdbased MR. However, in most cases, the existing models are not capable of describing the full distribution of heat and mass transfer processes taking place in MR.…”

Transient Hydrodynamics and Free Surface Capture of an Under-Baffled Stirred Tank During Stopping

“…The mixing behaviour depends not only on geometric parameters, such as the nozzle type, the reactor and baffles, and the agitator but also on fluid dynamic and physical properties. The mixing of an inhibiting agent in a stirred reactor has already been studied by various workers, e.g., Dakshinamoorthy et al (2004Dakshinamoorthy et al ( , 2006, Hristov and Mann (2002) or Kammel et al (1996), with an agitator continuously in rotation. A particularly interesting case, which has rarely been studied, is the mixing of the killer (or stopper) during the slow down and stopping phase of the agitator.…”
