This paper presents applications of a new model of the rheological behaviour of dense oil-inwater emulsions of non-colloidal droplets to describe the flow structure, the effects of the flow of dense emulsion on drop deformation and the related increase of the interfacial area and the mass transfer rate.

The paper presents an application of large eddy simulations to predict a course of precipitation process carried out in selected types of jet reactors. In the first part of this work the simulations results were validated using PIV and PLIF techniques and also by comparing model predictions with experimental data for fast parallel chemical test reactions. In the second part of this work predictions of modeling are compared with experimental data for BaSO4 precipitation. Precipitation model is tested in this part also by comparing predictions of the model based on LES with results obtained using the multiple-time-scale mixing model combined with the k‒e model.

Methods that can be used to predict agitation power of the in-line rotor-stator mixers are considered in this paper. Results of experimental investigations and CFD modeling are presented and interpreted theoretically for the Silverson rotor-stator (150/250) MS mixer. Results of theoretical analysis lead to extended version of previously used correlation.
