Haller discuss the advantages of using Q s < 0, as opposed to Q<0, in detecting regions of stretching in two-dimensional ﬂows (see also Haller 2001b). The Q s-criterion is objective and can be turned into a mathematically exact vortex deﬁnition for two-dimensional ﬂows. From road cars and caravans to race cars we can help with our aerodynamics consultancy services using CFD as the backbone for development.

Max Once the ignition criterion is fulfilled for a cell surface, fuel is released at a rate governed.

The first peak of Q criterion in Fig. 10(b) is consistent with that of Rortex. In Fig. 10(c) (Point 3), both Rortex and Q criterion deviate from 0.3 s due to the Using the decomposition into symmetric and anti-symmetric parts these invariants can be expressed as follows. P= tr(D ) Q= 1 2 (tr(D )2tr(D 2)) = 1 2 jj jj2jj S jj2. R= det(D ) 3.1.1 Q-criterion The Q-criterion de nes a vortex as a "connected uid region with a positive second invariant of ru"[14], i.e Q>0.
