Influence of wing planar shape on aerodynamic performance of flapping wing simulating mosquito

Abstract

We performed a numerical simulation of the flow field with wing flapping under conditions simulating mosquito flight. Several simple planar shape wing models with the same aspect ratio as that of an actual mosquito were considered. The wing models were treated as rigid, flat plates. The immersed boundary method was used to account for the wing model behavior. As results, the average aerodynamic forces generated by the real-shaped wing model did not exhibit the greatest value. When comparing the aerodynamic force divided by the wing area, the trend that the longer the wingtip chord length, the greater the force, was observed. Trapezoidal-shaped wing models with long chord lengths at the wing tip showed the highest overall performance.
