Direct numerical simulation (DNS) of flow past a vertical plate

Iso-contours of spanwise vorticity showing the first vortex shedding (due to the instability of a recirculation bubble) and the development of the periodic shedding modes in the initial stage of flow past a vertical plate. Direct numerical simulation (DNS) using Compressible Aerodynamics & Aeroacoustics Research coDe (CANARD) at Re=2,000 and M=0.25.

Wall-resolved large-eddy simulation (LES) of flow-induced acoustic resonance in a deep cavity

Iso-contour surfaces of perturbed pressure which show the coherent vortex structure travelling across the cavity opening and the resonant acoustic waves inside the cavity. Re=175,000. M=0.2.

Direct numerical simulation (DNS) of aerodynamic noise emanating from a stalled NACA0012 aerofoil:

Iso-contour surfaces of vorticity magnitude (flow structures) and dilatation field (acoustic waves) generated from a NACA0012 aerofoil at Re=50,000, M=0.4 and AoA=15 degrees, simulated by using CANARD (Compressible Aerodynamics & Aeroacoustics Research coDe)

Large-eddy simulation (LES) of compressible flow past a NASA SDT fan blade cascade, by using CANARD:

Iso-contour surfaces of streamwise vorticity (turbulent boundary layers) and the divergence of velocity (acoustic wave generation/radiation)

Large-eddy simulation (LES) of aerofoil noise generated from a serrated trailing edge:

Mean surface pressure fluctuation level, boundary-layer turbulence, and acoustic pressure radiation; comparing two different cases: one with a conventional and the other with a serrated trailing edge of a Joukowski aerofoil; Re=250,000; AoA=0

Direct numerical simulation (DNS) of flow through a channel with longitudinal ribs, by using CANARD:

Turbulent boundary layer behaviours inside the channel viewed from streamwise cross-section planes
