Lagrangian diffusion properties of a free shear turbulent jet
Bianca Viggiano, Thomas Basset, Stephen Solovitz +7
A Lagrangian experimental study of an axisymmetric turbulent water jet is performed to investigate the highly anisotropic and inhomogeneous flow field. The measurements were conduc…

Modelling Lagrangian velocity and acceleration in turbulent flows as infinitely differentiable stochastic processes
Bianca Viggiano, Jan Friedrich, Romain Volk +3
We develop a stochastic model for Lagrangian velocity as it is observed in experimental and numerical fully developed turbulent flows. We define it as the unique statistically stat…
