Abstract

Aerated mixing vessels are often used in chemical and biological industries. When the rate of gas absorption controls the rate of reactions, kLa is used as the design standard.
It was previously reported by the present authors that the overall vessel condition varied from bubbling-controlling condition at relatively high gas rates to agitation-controlling condition at relatively high impeller speeds via intermediate condition. According to this two-region model, kLa for the airwater system in the aerated mixing vessel has been correlated well in a wide range of operational conditions.
In this report, the two-region model is applied to Newtonian liquids with various physical properties and to non-Newtonian liquids, and reasonable dimensionless correlative equations are obtained.
