gradient flow

gradient flow

[′grād·ē·ənt ‚flō]
(meteorology)
Horizontal frictionless flow in which isobars and streamlines coincide, or equivalently, in which the tangential acceleration is everywhere zero; the balance of normal forces (pressure force, Coriolis force, centrifugal force) is then given by the gradient wind equation.

All these monitoring stations together will help to compute the gradient flow of glacier mass, surface velocity and the rate at which glacier accumulates and loses its mass.
It consists on the utilization of user-initialized curves that "evolve" inside the image until they find the contour sought for, taking advantages of different possible mechanisms, as B-splines, vector gradient flow and others.
The NanoLC System is the first HPLC (High Performance Liquid Chromatography) system to allow nanoscale LC/MS (liquid chromatography-mass spectrometry) without flow splitting, at gradient flow rates of 20-1000 nl/min.
Understanding of pressure gradient flows is also important from the point of view of flow and turbulence control.
The variety of scales proposed shows that a continuous effort is made to find universal scalings for adverse pressure gradient flows.
Five papers address such topics as variational methods and gradient flows in probability spaces; nonlinear elliptic equations and homogenization; and equations of parabolic-hyperbolic mixed type and elasticity.
