Studies were conducted' in 19-m3 fermentors (14-m3 working volume) using four Rushton turbines, four Prochem Maxflo Ts, and three Lightnin' A315s and the results in water have been reported earlier. Here, a 1.7 wt/vol% Xanthan solution has been used as the working fluid, simulating viscous broths to

## Abstract We consider a system of equations coming from turbulence models using a large eddy simulation (LES) technique. The idea of this approach bases on decomposing the velocity into a part containing large flow structures and a part consisting of small scales. The equations for largeβscale qu
Continuous culture fermentations of Escherichia coli W3110 have been carried out at controlled dissolved oxygen levels of 40% and 10% of saturation. Satisfactory and reproducible results were obtained. Agitation speeds of 400 and 1200 rpm at an aeration rate of 1 vvm have been used as well as an aer
In turbulent flow, the normal procedure has been to seek means u of the fluid velocity u rather than the velocity itself. If these means are defined by local spacial averaging with an averaging radius of β¦ the approach is known as large eddy Ε½ . simulation, and u denotes the eddies of size 0 β¦ and l
