🌀 Explore Turbulence with DNS, LES & RANS Simulation

Watch one Kolmogorov -5/3 turbulent velocity field get resolved three different ways: full DNS resolution, a spectrally-filtered LES with Smagorinsky subgrid viscosity, and a statistically time-averaged RANS mean field.

⚙ Under the hood

This simulation demonstrates the differences between Direct Numerical Simulation (DNS), Large Eddy Simulation (LES), and Reynolds-Averaged Navier-Stokes (RANS) turbulence modeling approaches. Users can adjust parameters to visualize how each method represents turbulent flow, from fully resolving all scales to employing statistical models of unresolved eddies.
