Impact of Wind Direction on Flow and Turbulent Statistics Over a Realistic Urban Area: A Large-Eddy Simulation Study
Josep M. Duró, Ernest Mestres, Ming Teng +2
Effects of wind direction in realistic urban canopies remain difficult to characterize systematically because local flow patterns, building-height variability, and turbulent statis…
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…
Impact of Wind Direction on Flow Over a Realistic Urban Area: A Large-Eddy Simulation Study
Ivette RodrÃguez, 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…
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…
Differentially heated turbulent channel flow two-point correlations
Marina Garcia-Berenguer, Lucas Gasparino, Oriol Lehmkuhl +1
This study analyzes the behavior of a differentially heated channel flow by means of a direct numerical simulations (DNS) with variable thermophysical properties under low-speed co…
Turbulent Boundary Layer in a 3-Element High-LiftWing: Coherent Structures Identification
Ricard MontalÃ, Benet Eiximeno, Arnau Miró +2
A wall-resolved large-eddy simulation (LES) of the fluid flow around a 30P30N airfoil is conducted at a Reynolds number of Rec=750,000 and an angle of attack (AoA) of 9 degrees. Th…
