Consequences of the close relation between Rortex and swirling strength
Popis výsledku v původním jazyce
Direct consequences stem from the close relation between the recently proposed vortex vector (Rortex) and the swirling strength. It is shownthat these vortex-identification methods share some relevant properties: (i) both provide the same and, practically, the largest vortex region,(ii) both allow an unlimited uniaxial stretching described by an axisymmetric strain rate, so the strain-rate magnitude inside a vortex maybecome much larger (without any limitation) than the vorticity magnitude, and (iii) both exhibit a discontinuous outcome, known as theso-called disappearing vortex problem.
