advection
Advection of warm moist air over a cooler surface, such as water, causes fog.

ad·vec·tion

 (ăd-vĕk′shən)
n.
1. The transfer of a property of the atmosphere, such as heat, cold, or humidity, by the horizontal movement of an air mass: Today's temperatures were higher due to the advection of warm air into the region.
2. The rate of change of an atmospheric property caused by the horizontal movement of air.
3. The horizontal movement of water, as in an ocean current.

[Latin advectiō, advectiōn-, act of conveying, from advectus, past participle of advehere, to carry to : ad-, ad- + vehere, to carry; see wegh- in Indo-European roots.]

ad·vec′tive adj.

advection

(ədˈvɛkʃən)
n
(General Physics) the transference of heat energy in a horizontal stream of gas, esp of air
[C20: from Latin advectiō conveyance, from advehere, from ad- to + vehere to carry]

ad•vec•tion

(ædˈvɛk ʃən)

n.
1. a shift in temperature, humidity, or the like resulting from horizontal movement of an air mass (disting. from convection).
2. the horizontal flow of air, water, etc.
[1905–10; < Latin advectiō=advec-, variant s. of advehere to convey (ad- ad- + vehere to carry) + -tiō -tion]
ad•vec′tive, adj.

advection

the horizontal movement of elements of the atmosphere. Cf. convection. — advective, adj.

Interface-capturing method consists of three methods: a method with a height function, a method with Lagrangian markers, and a method solving an advection equation.
considered the steady linear advection equation [13] and came up with coefficients, which also turned out to work well for the steady Euler equations.
After that, advection Equation 7 is solved with a semi-Lagrangian solver (Courant et al.
Even if the initial value of the level-set function [PHI] (x,0) is set to be the distance function, the level set function [PHI] may not remain as a distance function at t > 0 when the advection equation, Equation (6), is solved for [PHI].
Modern mathematicians recognize this eighteenth-century wonder worker with 21 papers on such diverse topics as Euler's work from 1750 to 1760, his fourteen most significant problems, his archives, his proof, with Bernoulli, of the fundamental theory of algebra, and his work on the quadrature of lunes, the Basel problem, elliptic integrals, harmonic progressions, power series expansions of the logarithmic and exponential functions, the summation formula, combinatories, the partition function, parallels with Clausen, the motion of the lunar apsides, elastic curves, the advection equation, the propulsion of ships and the creation of accurate maps.
The volume fraction is advected with the flow and satisfies the advection equation as follows:
