Passive Tracer Dispersion with Random or Periodic Source
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 ...
متن کاملNonlocal 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...

In this paper, the author investigates the impact of external sources on the pattern formation and long-time behavior of concentration profiles of passive tracers in a two-dimensional shear flow. It is shown that a time-periodic concentration profile exists for time-periodic external source, while for random source, the distribution functions of all concentration profiles weakly converge to a u...
متن کاملDispersion in the Surfzone: Tracer Dispersion Studies
Terrestrial runoff and river input dominates urban pollutant loading rates Often draining directly into the surfzone, this pollution degrades surfzone water quality, leading to beach closures (e.g., Boehm et al., 2002), increases health risks (e.g., diarrhea and upper respiratory illness) (Haile et al., 1999), and contains both human viruses (Jiang and Chu, 2004) and elevated levels of fecal in...
متن کاملPeriodic solution for a delay nonlinear population equation with feedback control and periodic external source
In this paper, sufficient conditions are investigated for the existence of periodic (not necessarily positive) solutions for nonlinear several time delay population system with feedback control. Nonlinear system affected by an periodic external source is studied. Existence of a control variable provides the extension of some previous results obtained in other studies. We give a illustrative e...
