Liquid circulation times were measured in a 40‐dm 3 concentric‐tube airlift fermenter with simulated media over a wide range of rheological properties. Circulation times decreased with increasing shear‐thinning, and the influence of draft‐tube geometry on circulation time was found to depend on the shear‐thinning of the media. A semi‐theoretical correlation for both Newtonian and non‐Newtonian fermentation media was developed.
