Sentence examples for incipient velocity from inspiring English sources

Sediment incipient velocity (SIV) is an important parameter for the rule of sediment movement and fluvial processes in the river sediment engineering.

The pulverized coal was extremely hard to be fluidized and its experimental incipient fluidizing velocity was much larger than expected.

Some general observations are discussed regarding the location and extent of scour events in bottomless culverts and incipient motion velocity variations between the bottomless arched culvert and a rectangular flume for the same substrate materials.

For turbulent flow in a pipe it is pertinent to consider a particle wholly within the viscous sub-layer, because it is isolated from significant turbulence and therefore hard to move; for such flow, the theory gives Eq. (21) to predict the critical pipe velocity, vC, for incipient motion of the hemisphere.

Here U is the fluidizing velocity; U= Umf at incipient fluidization.

Molecular excitations in liquids, recognized at the levels of melting, boiling, and critical temperatures, are replicated directly with larger particulate masses as velocities leading to incipient fluidization, elutriation and loss of phase distinction.

Methane catalytic combustion experiments have been performed in a 100 mm premixed fluidized bed reactor under lean conditions (0.15 3% inlet methane concentration), showing that complete CH4 conversion can be attained below 700 °C in a fluidized bed of 1 mm solids with a gas superficial velocity about twice the incipient fluidization velocity.

The critical flow velocity required to initiate incipient motion in the five test spheres of different dimensions was measured by acoustic Doppler velocimetry.

Values of U/Umf were in the range 0.0 3.6, where U is the superficial gas velocity and U= Umf at incipient fluidisation.

This work compares the fluid flow velocity required to initiate incipient motion of a particle predicted by a coupled CFD DEM model with measurements obtained during an experiment in an open channel under laboratory conditions.

This paper suggests a generalized correlation of critical velocity data based on dimensionless incipient fluidization (melting point) and terminal velocity (boiling point) correlants proposed in 1957.
