Thermally driven turbulent flows are omnipresent in nature and technology. A good
understanding of the physical principles governing such flows is key for numerous problems …

To quantify the fate of respiratory droplets under different ambient relative humidities, direct
numerical simulations of a typical respiratory event are performed. We found that, because …

We present STREAmS, an in-house high-fidelity solver for direct numerical simulations
(DNS) of canonical compressible wall-bounded flows, namely turbulent plane channel, zero …

While the heat transfer and the flow dynamics in a cylindrical Rayleigh-Bénard (RB) cell are
rather independent of the aspect ratio Γ (diameter/height) for large Γ, a small-Γ cell …

We report the observation of superstructures, ie, very large-scale and long living coherent
structures in highly turbulent Rayleigh-Bénard convection up to Rayleigh Ra= 10 9. We …

The ambient conditions surrounding liquid droplets determine their growth or shrinkage.
However, the precise fate of a liquid droplet expelled from a respiratory puff as dictated by its …

Turbulent flows laden with large, deformable drops are ubiquitous in nature and in a wide
range of industrial processes. Prediction of the interactions between drops, which deform …

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 …

We present an efficient solver for massively-parallel direct numerical simulations of
incompressible turbulent flows. The method uses a second-order, finite-volume pressure …

In thermal convection, roughness is often used as a means to enhance heat transport,
expressed in Nusselt number. Yet there is no consensus on whether the Nusselt vs Rayleigh …
