Wall-bounded turbulent flows can take different statistically stationary turbulent states, with
different transport properties, even for the very same values of the control parameters. What …

The coexistence of multiple turbulent states was reported in several recent studies in
different flows. We present in this work that multiple turbulent states also exist for thermal …

The mean flow behaviour of a turbulent boundary layer over rough walls is expected to
exhibit symmetries that govern the flow dynamics. In particular, when roughness elements …

In this study, we discuss the observed flow regimes in Taylor–Couette flow of radius ratio η=
0.1 for various Reynolds numbers up to 1.5× 10 4. We investigate the flow using a …

Turbulence is ubiquitous in nature and engineering applications. Although Kolmogorov's

Conflict between formation of a cyclonic vortex and isotropization in forced homogeneous
rotating turbulence is numerically investigated. It is well known that a large rotation rate of …

Emulsions are omnipresent in the food industry, health care, and chemical synthesis. In this
Letter the dynamics of metastable oil-water emulsions in highly turbulent (10 11≤ Ta≤ 3× …

Heating a quiescent fluid from below gives rise to cellular convective motion as the
temperature gradient becomes sufficiently steep. Typically, this transition increases heat …

We experimentally and numerically investigate the angular momentum transport in turbulent
Taylor-Couette flow for independently rotating cylinders at a small radius ratio of η= 0.357 for …

Using high-resolution particle image velocimetry, we measure velocity profiles, the wind
Reynolds number and characteristics of turbulent plumes in Taylor–Couette flow for a radius …
