Transport of pollutants in a river by bulk water flow downstream is an example of advection.
In this paper we investigate the spectral and evolutionary properties of relatively simple, linear, advection-diffusion equations.
Corresponding transverse variation is induced in the downstream periphery; however, it displays significantly greater axial advection due to the greater flow speed there.
However, in interpreting the results of chaotic advection, it must be recognized that solutes diffuse and solid particles move relative to the fluid locally.
At the outer edges of the plume, however, the production and destruction terms rapidly approach zero and advection and transport balance each other.
After the numerical advection step based on (4.2) and (4.3), we need to review the segment structure.
This formulation facilitates the usage of (nearly) nonoscillatory advection schemes for solving these equations numerically.
In this equation the nonlinear terms on the left side represent an advection of the quantity u with advective velocity (u, v, w).
Another desirable property of an advection scheme is the synchronous transport of fluid and tracers.
