| Abstract: | A method is developed and demonstrated for the prediction of liquid circulation velocity in airlift bioreactors operating with pseudoplastic fluids, including mould suspensions. The method is based on a combination of a recently developed energy balance over airlift loops with analytical expressions for shear stress in turbulent or laminar flow of non-Newtonian fluids. The procedure enables, an a priori calculation of pseudoplastic fluid circulation in airlift devices for design purposes. |
