The purpose of this study is to investigate flow pattern around mosquito's wing while it is beating. We constructed an experimental apparatus to simulate the beating motion of mosquito. An enlarged scale model experiment was carried out using a very low speed wind tunnel under the condition that Reynolds number and Strouhal number were made equal to those of real mosquito. The flow field around rectangular and realistic wing models moving up and down was visualized using smoke and laser light sheet and it was analyzed by a PIV system. It was observed that unsteady vortices were generated on the upper surface of the model wing in the period of downstroke. Further more, we made some experiments using a realistic wing model to simulate the real flapping motion.
