چکیده

In this paper, the author investigates the impact of external sources on the pattern formation and long-time behavior of concentration proles of passive tracers in a two-dimensional shear ow. It is shown that a time-periodic concentration pro le exists for time-periodic external source, while for random source, the distribution functions of all concentration pro les weakly converge to a unique invariant measure (like a stationary state in deterministic systems) as time goes to in nity.

Nonlocal Dynamics of Passive Tracer Dispersion with Random Stopping

We investigate the nonlocal behavior of passive tracer dispersion with random stopping at various sites in fluids. This kind of dispersion processes is modeled by an integral partial differential equation, i.e., an advection-diffusion equation with a memory term. We have shown the exponential decay of the passive tracer concentration, under suitable conditions for the velocity field and the pro...

The authors investigate the impact of external sources on the pattern formation of concentration profiles of passive tracers in a twodimensional shear flow. By using the pullback attractor technique for the associated nonautonomous dynamical system, it is shown that a unique time-almost periodic concentration profile exists for timealmost periodic external source. ∗This work was partly supporte...

Dispersion of passive tracer in the atmospheric convective boundary layer with wind shears: a review of laboratory and numerical model studies

Paper reviews recent laboratory and numerical model studies of passive gaseous tracer dispersion in the atmospheric convective boundary layer (CBL) with surface and elevated wind shears. Atmospheric measurement data used for validation of these two model techniques are briefly discussed as well. A historical overview is given of laboratory studies of dispersion in the atmospheric CBL. Model stu...

On the dynamical origin of asymptotic It* dispersion of a nondiffusive tracer in incompressible laminar flows

where the velocity field is periodic in one or more of the variables (x,y,z) with the remaining variables (if any) bounded (this setting can be relaxed, as we will explain later). The study of nondiffusing passive scalars has gained more attention in the past few years, and this is probably related to the interest in the notion of chaotic advection and stirring of fluids, which has largely been...
