contents The streamline pattern of planar polynomial velocity field is far from fully understood. In the community of fluid mechanics, most studies simply focus on the velocity gradient, or the linear part of the velocity field, but few studies on high-order terms. This paper is concerned with the local streamline pattern (LSP) of velocity field around an isotropic point. In virtue of the concept and method of dynamical systems, where the streamline pattern is equivalent to the phase portrait, we make clear the classification of LSPs of planar velocity fields with nonzero linear part, especially the cases where the determinant of velocity gradient vanishes at the isotropic point.
