The results of an experimental study of the heat flux in a model of a centrifugal vortex apparatus with a lower rotating disk are presented. An experiment considered three cases at a distance between the disks H=R/2 and H=R: “water”, “water-air

This paper describes the first experimental evidence of how vortex breakdown develops and disappears in both upper and lower fluids in a sealed vertical cylindrical container, where two immiscible fluids circulate driven by the rotating lid while oth

The paper analyses the typical topology of swirling flows of two immiscible fluids generated in the cylindrical container by its rotating end wall. Using the flow visualization and velocity measurements by PIV for different parameters of rotation of

Two-fluid swirling flows are rich in features of fundamental and practical interest. Among them, the most intriguing phenomenon that is important for applications is the formation of local circulation cells (vortex breakdown, VB). Our experimental st

This paper reviews counterflows, double counterflows, and circulation cells in swirling flows and argues that all these seeming paradoxical phenomena can be caused by a common swirl- decay mechanism (SDM). It is shown that SDM explains (a) the counte

A study is made of the steady-state flow of a viscous conducting incompressible fluid in a half-space, induced by an electric current spreading from a point source on a solid surface. There is a critical finite value of the current at which the veloc

The stability of Blasius and secondary flow is analyzed numerically. The resulting developed self-oscillatory regimes are calculated. The threshold characteristics for the development of three-dimensional structures thus obtained are in satisfactory

The axisymmetrical MHD — dynamo phenomenon and bifurcation of the azimuthal rotation have been found in conical self-similar flows of viscous incompressible conducting fluid. Such phenomenon is likely to bake place in some real MHD processes.

We propose a simplified theory of a viscous layer in near-wall turbulent flow that determines the mean-velocity profile and integral characteristics of velocity fluctuations. The theory is based on the concepts resulting from the experimental data im
