This paper proposes an adaptive streamline tracking method for two-dimensional CFD velocity fields. We assume that the multiplication of an unknown scalar function and the linear interpolation of a CFD velocity field satisfy the law of mass conservation and then derive the expressions of the scalar function. The adaptive streamline tracking method seeks more data in a cell of meshes when there are points at which the scalar function equals the infinity in the cell. Exact tangent curves for linear vector fields are used to draw streamline segments in triangles. Examples in the last section show that the adaptive streamline tracking method can be used to draw more accurate streamlines if we choose a larger threshold number.
