CREEPING COUNTER VORTEX FLOW
Pages 172-180
The authors have performed an analytical research into one of the most complex types of heterogeneous 3D flows of fluids and gases, that is, a creeping counter vortex flow. The “creeping counter vortex flow” is the flow that is formed as a result of interaction between two or more slow concurrent co-axial circulatory longitudinal flows swirling in the opposite directions.Creeping flows are typical for numerous structural elements of machines, mechanisms, items of equipment and devices, if the flow velocity or cross dimensions of channels are small or, alternatively, if the viscosity of the fluid is high. This model designed by the coauthors, serves as the basis for the hydrodynamic theory of lubrication. If the flow velocity is small and the viscosity of the liquid media is substantial, inertial convective summands can be ignored for Navier — Stokes equations.The coauthors believe that the research into the phenomena of the creeping counter vortex flow as one of the types of heterogeneous 3D flows of fluids and gases has a strong potential in space technologies, and it may be elaborated in further research projects to be developed by the coauthors.
