Stretching response of Rortex and other vortex-identification schemes

By considering a uniaxial stretching coupled with an inevitable uniform radial contraction for incompressible flow, a straightforward comparison of the stretching response for several popular vortex-identification criteria and the recently proposed vortex vector (Rortex) is presented. In addition, t...
