153 Introduction This report presents the results of a set of feasability'studies for observing Do-go mixing and CP violation in the proposed high luminosity r-charm factory. These studies are not yet complete, but clear general conclusions can already be drawn. In particular, a year of running with 1O33 luminosity would allow observation of Do-Do mixing at the level of IO-" to 10V5, consistent...

We investigate the temporal scaling properties of mixing in heterogeneous permeability fields with variances ranging from very small (σ lnK = 0.01) to very large (σ lnK = 9). We quantify mixing by the scalar dissipation rate, which we estimate over a large range of temporal scales. For an initial pulse line injection, we find that moderate and strong heterogeneity induce Preprint submitted to E...

This paper deals with the effects of mixing time on the homogeneity and dispersion performance of adhesive mixtures for inhalation. Interactions between these effects and the carrier size fraction, the type of drug and the inhalation flow rate were studied. Furthermore, it was examined whether or not changes in the dispersion performance as a result of prolonged mixing can be explained with a b...

Air sparging (AS) is a commonly applied method for treating groundwater contaminated with volatile organic compounds (VOCs). When using a constant injection of air (continuous mode), a decline in remediation efficiency is often observed, resulting from insufficient mixing of contaminants at the pore scale. It is well known that turning the injection on and off (pulsed mode) may lead to a better...

A model describing odor causing volatile organic compounds (VOC-odor) transport in a ventilated airspace influenced by heterogeneity of adsorption surface of ambient aerosol and air mixing pattern is proposed and analyzed based on a transfer function modeling technique. In this study an advection–reaction impulse/step response function for VOC-odor is assumed. The system process presented by an...

In order to study effect of complementary pulp distribution, computational fluid dynamic (CFD) was used to research flow characteristic of hydraulic headbox based on complementary pulp distribution. Mass flow rate out of mixing chamber and velocity distribution at slice of headbox were experimented. The results showed that because of simplified design, there were a little gradient of velocity a...

Laminar flow and mixing of a Newtonian fluid are characterized in a four-element Koch-Glitsch SMX static mixer. The computational analysis on a fine, unstructured mesh containing more than 3.5 million tetrahedral elements led to high-resolution numerical data for ®elocity and pressure. Computed pressure drops agreed excellently with those in the literature. The flow in this static mixer is esse...
