Many natural and industrial turbulent flows are subjected to time-dependent boundary
conditions. Despite being ubiquitous, the influence of temporal modulations (with frequency …

Extracting statistics for turbulent flows directly from the Navier–Stokes equations poses a
formidable challenge, particularly when dealing with unsteady or inhomogeneous flows …

Turbulent flows in three dimensions are characterized by the transport of energy from large
to small scales through the energy cascade. Since the small scales are the result of the …

A turbulent flow mixes in general more rapidly a passive scalar than a laminar flow does.
From an energetic point of view, for statistically homogeneous or periodic flows, the laminar …

This paper focuses on the effects of a space-time dependent periodic stirring of a moderately
turbulent planar co-flow jet configuration. The baseline flow is agitated in time and in space …
