Impact of Wind Direction on Flow Over a Realistic Urban Area: A Large-Eddy Simulation Study
Ivette Rodríguez, Josep Maria Duró, Ernest Mestres +2
We conducted high-resolution large-eddy simulations over a real urban district in Barcelona to examine the impact of wind direction on near-ground flow. The computational mesh reso…

Reduced-order modeling of large-scale turbulence using Koopman -variational autoencoders
Rakesh Halder, Benet Eiximeno, Oriol Lehmkuhl
Reduced-order models (ROMs) are very popular for surrogate modeling of full-order computational fluid dynamics (CFD) simulations, allowing for real-time approximation of complex fl…

Atmospheric boundary layer over urban roughness: validation of large-eddy simulation
Ming Teng, Josep M. Duró Diaz, Ernest Mestres +3
The study presents wall-modeled large-eddy simulations (LES) characterizing the flow features of a neutral atmospheric boundary layer over two urban-like roughness geometries: an a…
