In the outer layer, hairpin vortices occur in streamwise-aligned packets that propagate with smallvelocitydispersion.
From theCambridge English Corpus
In a young packet with only a few hairpins having nearly the same size, this means smallvelocitydispersion, and relatively slow downstream convection speed.
From theCambridge English Corpus

From theCambridge English Corpus
Because the groupvelocitydispersionof the grating leads to substantial temporal broadening of the harmonic pulses, the time resolution was limited to several picoseconds.
From theCambridge English Corpus
Overall, it appears that the stony meteorites fragment before substantial melting and vaporizing occur, with a significant amount of energy deposited into mechanical fracture andvelocitydispersion.
From theCambridge English Corpus
It is difficult, however, to estimate the mass of such faint objects due to significant foreground contamination, which inflates thevelocitydispersion.
