Chromatography of Latex Particles in Packed Columns (Hydrodynamic, Dispersion)
… with either nonporous packing material (termed hydrodynamic chromatography) or porous packing material (termed porous hydrodynamic chromatography or size exclusion chromatography) were studied.

Flow Dynamics in Large River Basins: Self -Similar Network Structure and Scale Effects
… generation, river-network geomorphology and the hydrodynamics of channel flow. In this research, the processes which contribute to the variance of the network hydrologic response are investigated by coupling the river network organization with hydraulic geometry relations, thereby relaxing the …

Improved understanding and prediction of the hydrologic response of highly urbanized catchments through development of the Illinois urban hydrologic model (IUHM)
… been shown in natural watersheds that there are dispersion mechanisms that contribute to the impulse response function of the catchment: hydrodynamic dispersion, geomorphologic dispersion and hydrodynamic dispersion. We introduce a fourth dispersion mechanism, intra-state dispersion, that …

Analysis of Flow and Transport in Refractive Index Matched Porous Media
… of the longitudinal and both transversal hydrodynamic dispersion coefficients. Whereas for the longitudinal dispersion a previously known power-law could be confirmed, the significantly different behavior of the transversal dispersion in vertical and horizontal direction has been observed …

Seasonal dynamics in costal aquifers : investigation of submarine groundwater discharge through field measurements and numerical models
… Circulation mechanisms such as tides, waves, and hydrodynamic dispersion cause significant saline groundwater discharge, and are potentially important for chemical loading to estuaries. However, these mechanisms can explain only 12-30% of the observed saline outflow in Waquoit Bay. A seasonal …

Numerical modelling of transport of pollutant through soils
… properties of the unsaturated soils and the dispersion characteristics need to be obtained for such an analysis. The unsaturated flow parameters are obtained from a functional relationship between capillary pressure head and moisture saturation, and can be determined from laboratory tests on …

Inorganic contaminant transport through unsaturated clay soil
… model which includes unsaturated flow, hydrodynamic dispersion, and physico-chemical reaction between the solid and the liquid phase, employing the theory of mass transport. The experimental investigation contains two main sets of laboratory tests: ( i ) some independent tests in order …

Characterization and modeling of soluble manganese removal from drinking water by oxide-coated filter media
… film transport, internal diffusion, and hydrodynamic dispersion were included, with sorption capacity apportioned into kinetically available and unavailable sites. The model performed well in calibration, predicting dynamic system response across a range of flow, pH, [Ca²⁺], and reactant …

Numerical investigation of ion transport mechanisms in electrochemical energy storage devices: Similarity correlation and exergy destruction analysis
… Poisson-Nernst-Planck formulation with hydrodynamic dispersion in porous media for the species transport. The RFBs modeled here can use either cost-effective non-selective separators or crossover reducing ion-exchange membranes. We also introduce Marcus-Hush-Chidsey kinetic theory based …

Bottom-up theoretical frameworks for upscaling transient mass transport in porous media
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2025-10-20 without embargo terms

Collective behavior of colloidal suspensions under electric fields and confinement
… density fluctuations. We also present results on hydrodynamic dispersion and velocity fluctuations, and their dependence on volume fraction is discussed. We then pay attention to two special cases. First, colloidal suspensions of spheres undergoing dielectrophoresis alone in a uniform AC electric …
