The purpose of this study is to clarify hydrodynamic characteristics of a human hand model. Three different models of an adult mene's right hand (Model A, thumb only opened ; Model B, all fingers spread ; Model C, all fingers closed) were made with polyester resin. The magnitudes of pressure acting on holes which were located at the hand model surface, were measured for various pitch angles using a wind tunnel test device. Moreover, the flow visualization of air around the model was conducted using the laser beam. By means of these pressure data, the magnitudes of fluid force were calculated. The experimental results reveal that the way in which the fingers are opened has a large influence on the fluid force over the entire hand. When the thumb side became a leadng edge, the Model A, thumb only opened seems to be advantageous for generating lift force. When the little finger leads, the Model C, all fingers closed can produce more lift force than other models.
