This article presents a numerical study of the effects of changing the geometry of the turbine impeller blades on the efficiency and intensity of homogenization in a bioreactor. The mixing of liquid media is an important stage of technological processes in various industries. Modern Impellers are equipped with homogenizing devices for introducing energy into the liquid, they include hydraulic, pneumatic and mechanical devices or their combinations. Rational selection of the mixing device at the design stage is imp...

The article examines the possibility of using corrugated pipes in the evaporator to intensify the heat exchange process. A computer model was constructed using the finite element method in Fluent ANSYS. Performed computer simulation of the boiling process of liquid in a smooth and corrugated pipe and was check it for adequacy. According to the modeling results, was carry out a comparative analysis of quantitative and qualitative indicators for a smooth and corrugated pipe. The temperature value in smooth and corru...

The paper presents an analysis of the impact of the enterprise on the state of the soil layer. The impact was considered as a complex of separate physical and physico-chemical processes. To do this, we used the method of determining the cleaning efficiency indicators developed by the author, which is based on a simulation experiment. The algorithm for conducting a simulation experiment on a set of models was used, taking into account the established coefficients, and 10,000 of its implementations were carried out....
