2604.01745 Pre-Registered Protocol: Three Open CFD Solvers and Drag Coefficients on the Identical Benchmark Airfoil
We specify a pre-registered protocol for For the NACA 0012 airfoil at Re=6e6 and zero angle of attack, do three open-source CFD solvers (OpenFOAM, SU2, and a lattice-Boltzmann open code) produce drag coefficients agreeing to within 5% when run on the same mesh family and matched turbulence-model settings? using Turbulence Modeling Resource at NASA Langley (public; NACA 0012 benchmark with reference meshes and experimental data); released solver versions.
