We revisit the issue of whether thermal fluctuations are relevant for incompressible fluid
turbulence and estimate the scale at which they become important. As anticipated by …

In turbulent flows, kinetic energy is transferred from large spatial scales to small ones, where
it is converted to heat by viscosity. For strong turbulence, ie, high Reynolds numbers …

Our understanding of turbulent boundary layer scaling and structure has advanced greatly in
the past 20 to 30 years. On the computational side, direct numerical simulations and large …

The energy spectrum of incompressible turbulence is known to reveal a pileup of energy at
those high wavenumbers where viscous dissipation begins to act. It is called the bottleneck …

A temporally evolving turbulent plane jet is studied both by direct numerical simulation
(DNS) and Lie symmetry analysis. The DNS is based on a high-order scheme to solve the …

The present study is concerned with breakup models for microbubbles in turbulent flows.
Analyzing the different physical mechanisms responsible for breakup based on a literature …

An experimental aeroacoustic study on the influence of the collective blade pitch angle in
the noise emissions by an isolated propeller under different turbulent inflow conditions is …

Time-resolved particle image velocimetry is implemented with a camera array and several
laser sheets; this results in a multi-spatio-temporal scale system that is modular and flexible …

A detailed study of the gas-dynamic behaviour of both liquid and gas flows is urgently
required for a variety of technical and process design applications. This article provides an …

Trailing suction hopper dredgers (TSHDs) are the main type of ship used for dredging
projects. However, the release of low concentration slurry poses challenges for the …
