In the past few decades various particle image–based volumetric flow measurement
techniques have been developed that have demonstrated their potential in accessing …

Understanding and predicting turbulent flow phenomena remain a challenge for both theory
and applications. The nonlinear and nonlocal character of small-scale turbulence can be …

abstract The output from a direct numerical simulation (DNS) of turbulent channel flow at Re
τ≈ 1000 is used to construct a publicly and Web services accessible, spatio-temporal …

In recent years, several techniques have been introduced that are capable of extracting 3D
three-component velocity fields in fluid flows. Fast-paced developments in both hardware …

Fluid flows are intrinsically characterized via the topology and dynamics of underlying vortex
lines. Turbulence in common fluids like water and air, mathematically described by the …

Quantifying deformation is essential in modern laboratory models of geological systems.
This paper presents a new laboratory monitoring method through the implementation of the …

Time-resolved tomographic particle image velocimetry experiments show that new hairpin
vortices are generated within a fully developed and unperturbed turbulent boundary layer …

The statistics of the velocity gradient tensor field, which is used to validate the stochastic
estimation and provide insights towards the model's refinement. Jointly, these approaches …

The super-temporal-resolution (STR) reconstruction of turbulent flows is an important data
augmentation application for increasing the data reach in measurement techniques and …

We propose and validate a novel experimental technique to measure two-point statistics of
turbulent flows. It consists of spreading rigid fibers in the flow and tracking their position and …
