Comparison between two computational fluid dynamics methods for gust response predictions

Based on the open-source computational fluid dynamics (CFD) platform, OpenFOAM, two numerical simulation methods for gusty inflow characterization and gust response prediction are implemented by solving the fundamental incompressible unsteady Reynolds averaged Navier–Stokes (URANS) equations. One is the Field Velocity Method (FVM) and the other is the Oscillating Vane Method (OVM). The gust velocity field is characterized and the aerodynamic responses of some airfoils under the Sears-type sinusoidal gusts are predicted by both gust simulation methods. The results indicate that both methods are capable of obtaining satisfactory gusty inflow conditions as expected as well as the airfoil aerodynamic responses. Comparatively, from the perspective of computing cost, the FVM is more advantageous in reducing the computational resources than the OVM while simultaneously ensuring the computational accuracy.
