Mass conservation is a key issue for constructing accurate streamlines of flow fields. We consider the CFD velocity fields without further data available such as the measured velocity fields. This paper presents a mass conservative streamline tracking method for such CFD velocity fields. Linear interpolation is used to approximate velocity fields and the exact tangent curve for linear vector fields is used to draw the streamlines. Demonstration examples in the last section show that the method is accurate.
