“…Both cases differ from the experimental streamlines [22], in that the jet appears to die out over a distance of 10 cm for the simulations, whilst the vortex above the impeller is observed to reach the wall for the experimental study. This feature of the flow is consistent with later investigations [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. However, it must be noted that the tank configuration modelled in [21] is markedly different with three impellers agitating the liquid.…”

“…The modelling of stirred tanks has been long established to characterise rotational flow [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. For the majority of numerical studies of stirred tanks the liquid surface is not considered to deform with agitation (i.e.…”

“…A mixer designed to serve this dual purpose of mixing and pumping is called a pump-mixer (Coplan et al, 1954). Though the pump-mixers are essentially used for producing dispersions of a liquid phase in another immiscible liquid phase, single-phase characteristics are equally important as, with the present status of computing hardware, a practical way of solving population balance in agitated vessels calls for pseudo-single-phase modeling to get the parameters that eventually control drop breakage and coalescence and hence dictate the drop size distributions (Alopaeus et al, 1999;Maggioris et al, 2000;Alexopoulos et al, 2002;Alopaeus et al, 2002). The two important design or performance parameters of a pump-mixer are its power consumption and head generation both of which are affected by several parameters which can be classified either as geometric or process parameters.…”

“…Knowledge of dispersed phase size distributions in liquidliquid and other multiphase processing equipment is required as a basis for the design and optimization of the hydrodynamic, mass transfer [1] and chemical reaction [2][3][4] performance of the system. Non-first order fluid-fluid reacting systems are particularly sensitive to the dispersed phase size distribution and interaction dynamics.…”
