The fractal structures that form in disperse systems are considered. Theoretical models of
fractal aggregation and the kinetics of coagulation of fractal aggregates are described. The …

We examine films, subject to evaporation, that contain particles. The volume fraction of
particles increases as solvent is removed up to a maximum value of close packing. The …

The fingering instabilities in vertical miscible displacement flows in porous media driven by
both viscosity and density contrasts are studied using linear stability analysis and direct …

The two‐dimensional (2‐D) isotropic simulations of Tan and Homsy [Phys. Fluids 31, 1330
(1988)] are extended to much broader and longer domains, and the 2‐D anisotropic …

Fluid mixing plays a fundamental role in many natural and engineered processes, including
groundwater flows in porous media, enhanced oil recovery, and microfluidic lab‐on‐a‐chip …

Rectilinear homogeneous miscible displacements with gravity override are analysed by
means of direct numerical simulations on the basis of the vorticity–streamfunction …

Two-and three-dimensional computations with a hybrid finite-difference/particle-tracking
technique are compared for unstable displacements. In both homogeneous and …

Viscous fingering is a well-known hydrodynamic instability that sets in when a less viscous
fluid displaces a more viscous fluid. When the two fluids are miscible, viscous fingering …

Viscous and gravitational fingering refer to flow instabilities in porous media that are
triggered by adverse mobility or density ratios, respectively. These instabilities have been …
