"velocity characteristics" is a correct and usable phrase in written English.
You can use it when referring to the speed or rate at which something happens or progresses. For example, "The car's velocity characteristics are impressive."
The velocity fields often show regions of more or less constant velocity separated by velocity characteristics.
Results from this study indicate a strong influence of the atomization pressures and the melt nozzle diameters on velocity characteristics.
The influence of spinning cup and disk atomizer configurations on droplet size and ejection velocity characteristics has been experimentally investigated.
This paper deals with the experimental and numerical simulation of a type of thunderstorm wind, namely the microburst, to study the outflow velocity characteristics.
Velocity characteristics have been investigated at various positions in the flow over flat terrain, and over simple topographic features, thereby yielding topographical speed-up factors.
Velocity characteristics and depths of the dilute debris flow downstream of the energy dissipation structure were also affected to some extent by variations in the width of the energy dissipation structure.
Results of the droplets velocity, characteristic diameters, liquid volumetric fluxes and reaction progress variable are compared with experimental data.
Also the functionalities of dispersion coefficient of bubble motion and velocity characteristic factor have been developed with operating variables.
These small amplitude oscillations were found to change with the penetration rate of the indenter tip which is related to an N-shaped hardness-indentation velocity characteristic.
Additionally, the dust cloud concentration changes the flame velocity characteristic at low oxygen levels and higher dust concentration is more limited the flame acceleration.
The influence of Helmholtz-Smoluchowski velocity (characteristic electro-osmotic velocity), couple stress length parameter (measure of the polarity of the fluid), Hartmann magnetic number, and electro-osmotic parameter on axial velocity, volumetric flow rate, time-averaged flow rate and streamline distribution are visualized and interpreted at length.
