Streamlines from strain rate tensor

[QUOTE="Orodruin, post: 5774077, member: 510075"] No. The strain rate tensor can be zero while maintaining a steady flow. Think a body of fluid in uniform translation and rotation. For a potential flow ##\vec v = \nabla \phi## for some ##\phi##. The gradient is always orthogonal to the level surfaces of a scalar function. The streamlines for an irrotational flow will therefore always be perpendicular to the potential surfaces. [/QUOTE]
