“…Large eddy simulations have shown to perform well in capturing the complexity of turbulent flows, better capability and accurate prediction of turbulent flows especially the dissipative characteristics in stirred tank among other turbulence models [1,3,8,9,11,15,16,18,22,23,30].…”

“…It is well known from the literature that large eddy simulation (LES) can predict excellently the time-averaged mean and turbulence flows (Derksen, 2001;Revstedt et al 1998, Yeoh et al, 2004Hartmann et al, 2004;Li et al, 2007;Jahoda et al, 2007;Tyagi et al, 2007;Yapici et al, 2008). It is also possible to solve the turbulence flow in stirred tanks directly using the exact Navier-Stokes equations without any modelling, but this requires a grid and time step that resolves even the smallest eddies.…”

“…More recently, new studies have been published on the complex hydrodynamics of mixing vessels, although in all cases the vessel dimensions were less than 0.5 m in height [4][5][6][7]. Nevertheless, there are less published articles and results available for industrial mixing vessels such as the fermentation vessel analyzed in this study.…”

The turbulent gas-liquid flow field in an industrial 100-m 3 stirred tank was calculated by using computational fluid dynamics based on the finite-volume method. Turbulent effects were modeled with the shear stress transport model, and gasliquid bubbly flow was modeled with the Eulerian-Eulerian approach using the Grace correlation for the drag force interphase momentum transfer. The relative motion between the rotating impeller and the stationary baffled tank was considered by using a multiple frames of reference algorithm. The effects of Rushton and pitched-blade impeller design parameters such as blade geometry, location, and pumping direction on the mixing performance were investigated. It was found that a combination of Rushton turbines with up-pumping pitched-blade turbines provides the best mixing performance in terms of gas holdup and interfacial area density. The approach outlined in this work is useful for performance optimization of biotechnology reactors, as typically found in fermentation processes.
