Variance and Skewness Evolution in Transient Taylor Dispersion

Abstract: his talk will report on a combined numerical, experimental, and theoretical study of the variance and skewness evolution for passive scalar particles transported in pipe and channel flows, with explicit differences between these two cases illustrated and explained. We will investigate the dependence of initial conditions and Peclet number in effecting evolution dynamics within the first diffusive timescale. Questions concerning how the properties of a given initial condition determine the time required for asymptotic theory to become valid will also be addressed.
