2D Flow field streamline visualization, as a classic visualization method, expresses the structure and characteristics of the flow field with continuous streamlines. In this paper, a streamline color mapping enhancement algorithm based on double-layer grid control is proposed, which can better display the flow field and its field intensity distribution. The distance of the streamline is controlled by the double-layer grid, the seed point is scattered in the largest blank seeding area, and the visual streamline diagram of different effects can be obtained by setting the density control parameters, vector illustration with more even color distribution. The results show that the algorithm in this paper can obtain more continuous streamline distribution, and the streamline distribution obtained by regional equalization color mapping can reflect more field intensity distribution characteristics of the flow field.
Key words: Flow visualization / Streamline placement / Grid control / Color mapping
