Sentences with phrase «velocity gradient»
The phrase "velocity gradient" refers to the change in speed or velocity of a moving object in relation to its position. It helps us understand how fast something is moving and how that speed changes as the object moves in different directions or locations. Full definition
The stretching of individual polymers in a spatially homogeneous velocity gradient was observed through use of fluorescently labeled DNA molecules.

The collimation occurs when the accretion column has a flat shape, and the effect is augmented by the vertical velocity gradient there, which reduces the resonant trapping of resonant photons along the magnetic field lines.
Moreover, we contend that the quality of the simulations using the Mixed - SGS approach are severely degraded by excessive dissipation that occurs when the dissipation of the scalar transport schemes is combined with the dissipation due to models for unresolved turbulence that depend on spuriously large velocity gradients produced by the central difference numerics used for momentum.
«If you reduce the velocity gradient, you can prevent the waves from getting excited,» notes Kramer.
You don't need to use either pressure or gravity to get the missing term, which is velocity gradient.
