Modelling friction and heat transfer in turbulent forced convection over porous lattices
Aneek Chakraborty, Stefan Hickel, Davide Modesti
We perform direct numerical simulations (DNS) to investigate how cubic-lattice porous substrates influence momentum and heat transfer in turbulent channel flows. The simulations sp…

Physics-Informed Acoustic Liner Optimization: Balancing Drag and Noise
Haris Shahzad, Stefan Hickel, Davide Modesti
We present pore-resolved Direct Numerical Simulations (DNS) of turbulent flows grazing over acoustic liners with aerodynamically and/or acoustically optimized orifice configuration…

Passive stabilization of crossflow instabilities by a reverse lift-up effect
Jordi Casacuberta, Stefan Hickel, Marios Kotsonis
A novel mechanism is identified, through which a spanwise-invariant surface feature (a two-dimensional forward-facing step) significantly stabilizes the stationary crossflow instab…
