Hydrodynamic StabilityFigure 1. Bluff-body wake. Saddle points multidimensional map: (a) ω0(k0,s0) and (b) r0(k0,s0), Re=35, 4 diameters downstream the body.Figure 2. Snapshots of the perturbation velocity field in the physical plane (y, z) normal to the streamwise direction, x. (a) Channel flow: Re = 10000, t...
04 Feb Linear Wave Packets
Linear Wave Packets Plane Poiseuille flowFigure 1. Localized wave packet in Plane Poiseuille flows with Re=1000. An impulsive initial condition, located at the channel mid-plane is obtained by linear superposition of 7380 waves. The longitudinal (α) and transversal (β) components of the polar wavenumber...
04 Feb Turbulent Mixing
Small-Scale Anisotropy in Turbulent Shear-less Mixing The Philofluid Research Group is dedicated to advancing the understanding of turbulence dynamics through both laboratory and numerical investigations. Our focus lies in the small-scale features of turbulence, which involve a complex range of scales, each governed by distinct physics....

Turbulent DispersionSection 1: Turbulent Dispersion Figure 1. Illustrates the dispersion pf the water droplets with an initial monodispers size distribution (droplet diameter: 15 microns) in a mixing process under stable stratification. The evolution of the dispersion over 25 eddy turnover times can be observed in the...
