Previously, it has been shown that the dynamic geometric configuration of the flow channel of the left heart and aorta corresponds to the direction of the streamlines of swirling flow, which can be described using the exact solution of the Navier–Stokes ...

On Flow Reversal in Turbulent Swirling Flow
Summary: A turbulent swirling flow is studied with the aid of a variational method. The mean-flow field is expressed by the mean vorticity proportional to its curl. The total axial flux and total helicity per unit length are introduced to characterize the swirling flow, and the condition for the reversal of the axial flow near the center of flow is ...

Combustion in swirling flows: A review
Melting and burning of suspended alkane droplets are studied experimentally under electric field. It is found that the melting rate substantially decreases if electric field strength exceeds some critical value. It is about 60 kV/m under our experimental conditions.

THE PURPOSE. Determination of the optimal law of swirling of the blades of the last stage of a stationary GTU. Due to the specificity of its operating conditions - in a system with a diffuser - the traditional laws of swirling lead to a non-optimal flow ...

Stochastic Chaos in a Turbulent Swirling Flow [PDF]
We report the experimental evidence of the existence of a random attractor in a fully developed turbulent swirling flow. By defining a global observable which tracks the asymmetry in the flux of angular momentum imparted to the flow, we can first reconstruct the associated turbulent attractor and then follow its route towards chaos.

Distribution of motion scales of vortices in turbulent open channel flow
To understand the distribution of motion scales of vortices in turbulent open channel flow along water depth. A flume experiment system based on high-resolution particle image velocimetry(PIV) was applied to measure fully developed turbulent open channel
