论文名称：Aerodynamic effects of corrugation in flapping insect wings in hovering flight

发表刊物：The Journal of Experimental Biology

摘要：We have examined the aerodynamic effects of corrugation in model insect wings that closely mimic the wing movements of
hovering insects. Computational fluid dynamics were used with Reynolds numbers ranging from 35 to 3400, stroke amplitudes
from 70 to 180deg and mid-stroke angles of incidence from 15 to 60deg. Various corrugated wing models were tested (care was
taken to ensure that the corrugation introduced zero camber). The main results are as follows. At typical mid-stroke angles of
incidence of hovering insects (35–50deg), the time courses of the lift, drag, pitching moment and aerodynamic power coefficients
of the corrugated wings are very close to those of the flat-plate wing, and compared with the flat-plate wing, the corrugation
changes (decreases) the mean lift by less than 5% and has almost no effect on the mean drag, the location of the center of
pressure and the aerodynamic power required. A possible reason for the small aerodynamic effects of wing corrugation is that
the wing operates at a large angle of incidence and the flow is separated: the large angle of incidence dominates the corrugation
in determining the flow around the wing, and for separated flow, the flow is much less sensitive to wing shape variation. The
present results show that for hovering insects, using a flat-plate wing to model the corrugated wing is a good approximation.
