【Abstract】 Streamline visualization is an important technique for flow field visualization. The streamline visualization model based on the streamline function and the fluid flow velocity decomposition was put forward. The protract theory to identify the outflow surface of fluid flow based on the streamline function and the fluid flow velocity decomposition was elaborated. The method to gain the position of the outflow surface of fluid flow based on the streamline function was given. The connection curves between two points for various conditions were derived. The streamline protract program based on my streamline visualization model was developed. The location conditions of flow field in the protract example are accurately shown.更多还原
