The central vortex is formed on the central axis of the vortex chamber, so its deviation from the geometric center of the chamber а equals zero. Hello, According to the definition, the Q-criterion defines vortices as areas where the vorticity magnitude is greater than the magnitude of the rate of strain. The Q criterion is written as Q = 0.5*(vorticity2 – strain rate2) > 0 meaning relative dominance of the rotational component over the stretching component in deformation of a fluid element. Once you defined Q, you can generate iso-surfaces of Q for several positive values.Īccording to the definition, the Q criterion defines vortices as areas where the vorticity magnitude is greater than the magnitude of the rate of strain.

Re: how to plot Q criterion in fluent Q = 0.5(W*W – S*S) where W is the vorticity magnitude (you can find it under the “Velocity” menu) and S is the mean rate-of-strain (you can find it under “Derivatives” menu).
