| Research Abstract |
To know the effect of unsteadiness on the estimation of propulsive force, we measured the time varying flow fields around a hand. PIV (Particle Imaging Velocimetry) covering a wide range of flow fields was developed to the measurements. The visualization technique combined with motion analysis was applied to obtain an understanding of the mechanism of force generation. It was found that the generation and shedding of vortices play an important role in the generation.
