The Laboratory of Computational Fluid Dynamics started in 2002. Since the establishment of the Laboratory, it has been headed by Prof. Tatyana Petrovna Lyubimova, Doctor of physical and mathematical sciences. The laboratory fundamental research is concentrated on studying the influence of different non-stationary fields, such as vibration, electromagnetic fields, and rotation, on the behavior of non-uniform hydrodynamic systems under terrestrial and microgravity conditions.
Much attention is paid to the development and implementation of new numerical methods, high-performance parallel computing algorithms, and to the creation of software application packages. Numerical modeling results are used in preparation for both ground-based and space experiments and are essential for interpreting the data obtained during these experiments. The laboratory team took part in designing the space experiment IVIDIL (Influence of Vibrations on Diffusion in Liquids) focused on studying the influence of vibration on the separation of binary mixtures and the experiment DCMIX (Diffusion Coefficient Measurements in Ternary Mixtures), where transport processes in a three-component liquid mixture were studied. The experiments were conducted on the International Space Station, the European sounding rockets and the Russian satellite Foton. The research team was also involved in data processing.
The experience gained by laboratory researchers in the field of hydrodynamics of multiphase media provides a foundation for creating vibrational phase separation technologies. Technological solutions for the flotation separation of multicomponent ores into mineral fractions are currently being developed in cooperation with the Laboratory of Organic Complexing Reagents of the Institute of Technical Chemistry UB RAS. They rely on a comprehensive theoretical and experimental analysis of the influence of ultrasound on the interaction of bubbles with mineral particles in a liquid in the presence of flotation reagents.
Research on modeling the dynamics of water masses and the propagation of pollutants in large surface water bodies, considering density effects, is performed jointly with the Laboratory of Land Hydrology Problems of the Mining Institute UB RAS. Laboratory achievements have solved some environmental issues, such as reduction of water hardness at the Chusovskoy water intake (Perm) and disposal of excess brines of potash plants, that affect the Perm Krai economy, and, as a consequence, the economy of the Russian Federation.
