SUMMARY: (Tokyo Institute of Technology and Chiba University\, Japan): Quan
 titative estimates in the fluid dynamics of bristled wings of small insect
 s
DESCRIPTION:: Some smallest insects have fringed wings with long bristles (
 setae) visually resembling bird feathers. They are active fliers\, which i
 mplies that bristled wings produce enough force to support the animal body
  weight and propel it through the air. Aerodynamic function of the bristle
 d wings is a curious topic for its biological context as well as for the p
 eculiarities of the air flow conditions. In this regard\, experiments and 
 numerical simulations have been carried out to evaluate aerodynamic force 
 generation capacity of the wings of a miniature featherwing beetle Paratup
 osa placentis. The aerodynamic force coefficients have been determined fro
 m a dynamically scaled force measurement experiment with rotating bristled
  and membrane wing models in a glycerin tank. They have been used as numer
 ical validation data for a computational fluid dynamics simulation using a
 n adaptive Navier-Stokes solver. The latter has provided point-wise inform
 ation about the flow field\, thus allowing to evaluate flow parameters suc
 h as leakiness and permeability\, and gain an understanding of the underly
 ing fluid-dynamic mechanisms.\nDr. Dmitry Kolomenskiy\, Tokyo Institute of
