In the outer layer, hairpin vortices occur in streamwise-aligned packets that propagate with small velocitydispersion. In a young packet with only a few hairpins having nearly the same size, this means small velocity dispersion, and relatively slow downstream convection speed. The velocitydispersion of the turbulence is up to 10 times larger than the sound speed. Because the group velocitydispersion of the grating leads to substantial temporal broadening of the harmonic pulses, the time resolution was limited to several picoseconds. Overall, it appears that the stony meteorites fragment before substantial melting and vaporizing occur, with a significant amount of energy deposited into mechanical fracture and velocitydispersion. It is difficult, however, to estimate the mass of such faint objects due to significant foreground contamination, which inflates the velocitydispersion.

A central velocitydispersion refers to the of the interior regions of an extended object, such as a galaxy or cluster.

When a wave propagates through subsurface materials both energy dissipation and velocitydispersion takes place.

We can also use the principle of hydrostatic equilibrium to estimate the velocitydispersion of dark matter in clusters of galaxies.

The phenomenon of velocitydispersion leads to a rich variety of experimentally observable waveforms when acoustic waves propagate in plates.

The bulge component is similar to elliptical galaxies in that it is pressure supported by a central velocitydispersion.

The most important condition is "anomalous group velocitydispersion", whereby pulses with shorter wavelengths travel with higher group velocity than pulses with longer wavelength.

The result of group velocitydispersion, whether negative or positive, is ultimately temporal spreading of the pulse. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Low dispersion glasses are also employed in handling ultrashort pulses of light, in e.g. mode-locked lasers, in order to prevent pulse broadening by group velocitydispersion in the optical elements.

In other contexts, it may refer to the mass inferred from the rotation curve or velocitydispersion of a bound collection of stars, assuming the virial theorem applies.
