Abstract

The paper deals with a topic of current interest – the problems of blending and simultaneous aeration of liquids. Modeling research making use of a number of blending propellers of different geometry was conducted towards improving the parameters of a dedicated aeration facility which employed an axial impeller - specifically, a propeller having 50 mm in diameter. The energy related parameters of blending were examined experimentally and were confronted with patterns obtained by visualizing the process of agitation of the liquid being aerated. Based on this model research, an optimal option of the 50 mm propeller was established for production purposes. Subsequently, a corresponding propeller having 80 mm in diameter was designed and manufactured based on a confirmed affinity relation of the propeller input power. A laboratory testing facility was used to carry out both qualitative and quantitative comparisons of two alternative designs of the 80 mm propeller, and the basic data required for the selection of a suitable type of propeller were established.
