Nanoscale zerovalent iron (NZVI) rapidly transforms many environmental contaminants to
benign products and is a promising in-situ remediation agent. To be effective, NZVI should …

Flocculation of suspended cohesive sediment, well-known to impact the floc size distribution
and vertical fluxes, and cause morphodynamic changes of marine and riverine …

Nano-and micrometer particles tend to stick together to form agglomerates in the presence
of attractions. An accurate calculation of the drag and lift forces on an agglomerate is a key …

Although recent experiments have revealed that nanofluids have superior thermal
conductivities to base fluids, the inherent physics are not fully understood. In this study, an …

While the fractal dimension of suspended flocs of cohesive sediment is known to vary with
the shear rate, electrochemical properties of the sediment and environment, geometrical …

The drag force on aggregates and partially sintered agglomerates is assessed using the
lattice Boltzmann method (LBM) and accelerated Stokesian dynamics (ASD). Both methods …

Controlled dispersion of therapeutic agents within liquid-and gel-filled cavities represents a
barrier to treatment of some cancers and other pathological states. Interstitial delivery is …

An accurate drag correlation accounting for multiscale heterogeneous porous structures is a
prerequisite for reliable CFD simulation of fluidized beds. Though particle clusters in …

The hydrodynamic properties of rigid fractal aggregates are key ingredients in
understanding the governing mechanism of their motion and the properties of their …

The aim of this study is to analyze the flow and heat transfer inside a straight tube filled with
porous medium analytically and numerically. Steady incompressible viscous fluid flow …
