Control of separated turbulent stream by high.frequency rotary oscillations at RE=1,4×10⁵

Relevance. Characteristics of separated turbulent streams are of great importance when designing effective hydroand thermal power plants equipment. In such streams the flow regimes with harmful quasi-periodic high-amplitude oscillations of velocity and pressure behind the body are implemented. Thus, the knowledge on the ways of controlling...

'T-RANS' simulation of deterministic eddy structure in flows driven by thermal buoyancy and Lorentz force

The paper reports on the application of the Time-dependent Reynolds-Averaged Navier-Stokes (T-RANS) approach to analysing the effects of magnetic force and bottom-wall configuration on the reorganisation of a large coherent structure and its role in the transport processes in Rayleigh-Benard convection. The large-scale deterministic motion is...
