摘要：

The longitudinal dispersion for a fractal time random walker being dragged by a solvent flowing through a tube is studied by means of the Langevin and Fokker-Planck formalisms. One observes that for asymptotic long times the dispersion is superdiffusive despite the fact that in a resting background the characteristic diffusion regime is subdiffusive. The resulting behavior is also at variance with the standard diffusive behavior obtained in Taylor dispersion for a Brownian walker.
