ANALYSIS OF THE INFLUENCE OF THE GEOMETRY OF THE BLADE MIXER ON THE TURBULENCE AND INTENSITY OF LIQUID MIXING

Abstract

Turbulent fluid mixing is an important aspect of many industrial and technological processes where efficient mixing of various components is of paramount importance to achieve the desired results. Optimal mixing can improve product quality, ensure the unity of complex reactions, and reduce process lead times. In this regard, the study and understanding of the influence of the geometry of the mixer on the characteristics of the turbulent flow becomes an urgent task of scientific research. The relevance of the study is explained by the wide application of mixers in industrial and technological processes, where the efficiency of mixing is crucial for achieving optimal results. The work used methods of experimental and numerical modeling of turbulent flow in various geometric configurations of blade mixers. Indicators such as turbulence intensity, pressure gradient, and fluid mixing ratio were used to quantify the turbulent characteristics. The obtained results demonstrate that the geometric configuration of the blade mixer has a significant effect on the formation of the turbulent flow. Some geometric parameters of the mixer can contribute to increasing the intensity of liquid mixing, while others can reduce its efficiency. Scientific results can be useful for designing optimal paddle mixers for specific industrial tasks that require intensive liquid mixing. The use of optimized mixers can help increase process productivity, save energy resources, and improve product quality.
