A 2D flow simulation of a flapping wing “Golden Snitch” with wing boundary fed from stereo-photography measurement is firstly conducted in this paper. The whole research framework is shown in Figure 1. Softwares Matlab, Surfer, and Gambit were used to slice a quarter-span cross section from the previous 3D trajectory of Figure 2 as the 2D solid boundary for the quasi-steady CFD simulation by Fluent. The time-varying outputs include the 2D flow fields in Figure 3 and the corresponding lift coefficient. The one cycle history of lift coefficient subject to 14 Hz flapping is qualitatively similar to the wind tunnel data.
