Wake characteristics associated with logjams to inform river restoration
… impact habitats, important parameters include solid volume fraction (SVF) and channel width. Thus, these two variables were varied in 8 constructed logjams. The wake generated by each logjam was analyzed in a recirculating flume for velocity, turbulence, and fine sediment deposition. All …

Heat transfer in nano/micro multi-component and complex fluids with applications to heat transfer enhancement
… simulation that models the free movement of the solid particles suspended in the flow and its effect on the temperature distribution. Parallel implementations are done using MPI (message passing interface) method. Convective heat transfer in internal suspension flow (low solid volume fraction, …

Impacts of vegetation-generated turbulence on sediment transport
… crit] decreased with increasing vegetation solid volume fraction. This was attributed to the vegetation-generated turbulence, which induced a local, vertical, adverse pressure, or a lift force on the sediment grain, facilitating sediment transport. In contrast, the turbulent kinetic energy …

Computational Studies of the Mechanical Response of Nano-Structured Materials
… of metallic bicontinuous lattices with varying solid volume fraction, connectivity, size, surface stress, loading procedures, and solid density. Strain localization and yield response on nanoporous gold lattices as a function of their solid volume fraction are investigated in axially strained …

Velocity fluctuations in slow flow through porous media
… the swirls have a power-law dependency on the solid volume fraction, the correlation length is finite and has also a power-law dependency. I demonstrate that this scaling behavior is consistent with the predictions of theories. Finally, I study creeping flow through a single rough walled …

Flow and solute transport in random cylinder arrays : a model for emergent aquatic plant canopies
… contribution to the drag coefficient, the solid volume fraction, and the integral length scale of turbulence normalized by d, is then confirmed with our laboratory measurements. Our laboratory experiments demonstrate that Kyy/ (<u>d), the asymptotic (Fickian) lateral dispersion coefficient …

Colloidal and Polyelectrolyte Inks for Direct -Write Assembly of 3D Periodic Structures
… In addition, the inks must contain a high solid volume fraction to minimize drying-induced shrinkage after assembly is complete. First, a model colloidal ink based on monodisperse silica microspheres was designed for 3D periodic structures. These colloidal inks suffer difficulties (e.g., …

Structural property relation in improving chemically and physically crosslinked hydrogel surface properties
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2024-03-01 without embargo terms

Direct numerical simulation of viscoplastic particulate flows
… as additional particles, increasing the apparent solid volume fraction, and extend an existing micro-mechanical model to take this in to account.

Heterogeneous flow structure and gas-solid transport of riser
… aims to understand physical mechanisms of gas-solid transport and riser flow, investigate heterogeneous flow structures of gas-solid transport and their formation mechanism of the in riser flows, both in axial and radial directions. It provides sound interpretation for the experimental …

Thermo-mechanical characterisation of energetic materials for additive manufacture
… materials as uncured pastes comprising a high volume fraction of solid energetic particles dispersed in a liquid polymer resin. Initially, a new framework for considering the "printability" of energetic materials is proposed, in which different physical and rheological properties of the …

Effects of plasma proteins on the sieving of macromolecular tracers in the kidney
… different sizes or shapes, we used an excluded volume approach. In this formulation, which describes steric interactions only, partition coefficients were computed by summing all volumes excluded to a solute molecule by virtue of its finite size, the finite size of other solutes, and the …
