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...
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....

Students Visualizationsa) Visualization of an unsteady hot plume and turbulent jet This image captures the visualization of an unsteady hot plume and turbulent jet by means of white smoke statistical analysis, which was done during the course Turbulent Flows, Physics Laboratory 3 -DISAT on 29/11/2024. The...
Revisiting Atmospheric Diffusion at the Cloud-Clear Air Interface Numerical Simulation cloud-clear air interfacesDirect numerical simulations (DNS) of a decaying turbulent layer at a cloud top reveal enhanced diffusivity in the mixing region between cloudy and clear air. In this research, we build upon the foundational work...
BALLANSE Introduction, objectives and overview of the research programme BALLANSE puts forth a novel platform for Lagrangian observation of the Atmospheric Boundary Layer to be implemented in synergy between Meteorological Observatories, Numerical Weather Prediction, Clusters of air-floating Biodegradable Radiosondes. The atmosphere in the layers close to the...
We were honored to attend an insightful seminar at Politecnico di Torino, led by Prof. Silvano Massaglia, coordinator of the Philofluid research group in the DISAT department. The session focused on normal and active galaxies, the Black Hole paradigm for active galaxies, and the fascinating...
