Critical assessment of RANS Models for Turbulent Heat Transfer in Low-Prandtl-Number Forced Convection
Luca Marocco, Jonathan Schmitt, Jonathan Neuhauser +2
RANS modeling of turbulent heat transfer in liquid metals remains challenging because the very low Prandtl number weakens the similarity between momentum and thermal transport. Sev…

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…

Turbulent skin-friction drag reduction via spanwise forcing at high Reynolds number
Davide Gatti, Maurizio Quadrio, Alessandro Chiarini +2
We address the Reynolds-number dependence of the turbulent skin-friction drag reduction induced by streamwise-travelling waves of spanwise wall oscillations. The study relies on di…
