Research Highlights
- The position of the first groove microstructure affects the
aerodynamic performance of the airfoil.
- The pressure difference of different corrugation patterns shows
significantly asymmetric during the upstroke and downstroke.
- The aerodynamic is optimal of 2D-TWA models, when the number of
corrugations is 5, the corrugation is right angle and the flapping
frequency is 75 Hz.
