Scaling patch analysis of turbulent kinetic energy budget equation in wall-bounded flows
Tie Wei, Zhaorui Li, Sergio Pirozzoli
The scaling patch approach is applied to analyze the turbulent kinetic energy (TKE) budget equation in wall-bounded turbulent flows. The balance of the TKE equation is divided into…
Air entrainment and gas transfer processes in wave breaking events
Simone Di Giorgio, Sergio Pirozzoli, Alessandro Iafrati
We investigate gas transfer processes occurring at the air-water interface of progressive water waves using high-fidelity numerical simulations. Waves with varying initial steepnes…
A Chimera method for high-fidelity simulation of turbulent flows
Andrea Di Mascio, Sergio Pirozzoli
We develop a block-structured solver for high-fidelity simulation of flows in complex geometries, based on overlapping (Chimera) meshes. The key components of the algorithm are a b…
Simulation and modelling of convective mixing of carbon dioxide in geological formations
Marco De Paoli, Francesco Zonta, Lea Enzenberger +2
We perform large-scale numerical simulations of convection in 3D porous media at Rayleigh-Darcy numbers up to . To investigate the convective mixing of carbon dioxi…
The aerodynamic performance of a transonic airfoil with spanwise forcing
Niccolò Berizzi, Davide Gatti, Giulio Soldati +2
Spanwise wall forcing in the form of streamwise-travelling waves is applied to the suction side of a transonic airfoil with a shock wave to reduce aerodynamic drag. The study, cond…
Friction and heat transfer in forced air convection with variable physical properties
Davide Modesti, Sergio Pirozzoli
We establish a theoretical framework for predicting friction and heat transfer coefficients in variable-properties forced air convection. Drawing from concepts in high-speed wall t…
