Multiscale Turbulence Synthesis: Validation in 2D Hydrodynamics
Pierre Lesaffre, Jean-Baptiste Durrive, Jean Goossaert +5
Numerical simulations can follow the evolution of fluid motions through the intricacies of developed turbulence. However, they are rather costly to run, especially in 3D. In the pa…
