Helicopter Rotor CFD Simulation: Why Most Simulations Fail Before They Even Start
Most helicopter rotor CFD simulations fail long before solver convergence—not because of turbulence models, but due to poor mesh topology and vortex dissipation. This article explores how structured meshing, overset grids, wake preservation, DES turbulence modeling, and high-order schemes determine the accuracy of rotorcraft aerodynamic simulations.
