advection

the transference of heat energy in a horizontal stream of gas, esp of air

advection

[‚ad′vek·shən]
(meteorology)
The process of transport of an atmospheric property solely by the mass motion of the atmosphere.
(oceanography)
The process of transport of water, or of an aqueous property, solely by the mass motion of the oceans, most typically via horizontal currents.

advection

A method of heat transfer by horizontal movement of air or fluid. Unlike convection, where heat transfer takes place because of vertical movement, here the horizontal movement is the cause. When cold air comes into contact with warm ground or water, it heats up because of advection.

8) In the density function method, the color function, whose value jumps from 0 to 1 across an interface, is defined, and the advection equation of the color function is solved to capture a gas-liquid interface.
Since it is caused by the nonlinearity of the advection equation, the numerical diffusion is controlled effectively by a higher-order calculation scheme of advection.
to come up with optimal coefficients for that discretization, again for the steady linear advection equation and demonstrated that these work reasonably well for the steady Euler equations.
For instance, solving the advection equation first eliminates an extra projection function, and can reduce the computing time by 23% (Zuo 2010).
