Agglomeration effects, observed during precipitation of barium sulphate in the unpremixed feed two‐dimensional tubular precipitator, are studied experimentally and interpreted theoretically. Effects of process parameters on precipitation–agglomeration phenomena are predicted using a CFD based model that describes micromixing (the multiple‐time‐scale turbulent mixer model is used) and precipitation (including nucleation, growth and agglomeration of crystals). Agglomeration rate is defined as a product of the collision frequency and the probability of agglomeration.
