The study of vortex flows and vortex phenomena is performed in several directions. We developed the phenomenological theory of a turbulent flow in a centrifugal force field. The zones of turbulence damping or intensification in a vortex flow were revealed and described. This theory was confirmed by experimental data for a wide class of flows with a longitudinal curvature of streamlines. For example, in the flow with a curved surface, the swirl flow in a tube or a vortex chamber, semibounded vortex jets, and boundary layers in a rotating system. The discovery of the phenomenon of a stable dispersed layer of heavy particles which «hangs» in a swirled flow was patented.
   We studied the influence of an organized vortex structure on the process of anomalous separation of the mixture. The active investigation of Ranque's effect (i.e., the temperature separation in a vortex tube) is carried out.
    The problem of spontaneous generation of a rotation in liquid flows was thoroughly examined for several different cases: a submerged jet, a flow between two porous disks, and a flow through a ring channel. The formation of large-scale concentrated vortices (alike vortex filaments) was discovered in intensively swirled flows. We developed a theory for these vortices which has a significant fundamental value. Vortex structures are of great importance for a developed turbulent flow not only on a large scale, but also for a small scale of inertia intervals which exhibit themselves in the intermittence phenomenon. We used the methods of the quantum field theory and the re-normalization group methods to obtain completely new results.
    The random dynamics of quantisized vortex filaments was studied using analytical and computational methods. We elaborated the Gaussian model of a random vortex tangle in a superfluid turbulent He II. We wrote and solved equations for the dynamics of a powerful heat impulse generating quantisized vortices. The fast and slow modes in superfluid turbulent flow were separated.
    We developed a theoretical foundation for designing vortex apparatus used for power generation, chemical technologies, and oil and gas industries.
