A hybrid numerical model previously developed for combustion simulations is extended in this article to describe flame propagation and stabilization porous media. The model, with a special focus on flame/wall interaction processes, validated via corresponding benchmarks involving channels both adiabatic constant-temperature walls. Simulations different channel widths show that the can correctly...

Recently, the trend towards sustainable energy production and pollution control has motivated increased consumption of ultra-low-sulfur diesel (ULSD) or bio-fuels. Such fuels have relatively low surface tension with water therefore, separation from fuel become a challenging problem. The process relies on using porous structures for collection removal droplets. Hence, understanding interaction b...

The recent emergence of multi-drug resistant bacteria has rendered many common antibiotics ineffective and therefor novel drugs are needed. Antimicrobial peptides have proven applicable in this aspect as they can form self-assembled pore structures in the lipid bilayer of bacterial cells. The exact pore formation is shrouded in controversy and largely unknown as it is difficult to determine emp...

NMR is a popular logging technique used to estimate pore size information, formation permeability, wettability and irreducible water saturation. Quantitative interpretation of NMR data is based on a set of fundamental assumptions (e.g., pore isolation and fast diffusion). These assumptions establish the quantitative link between NMR response and petrophysical predictions. While there is a need ...

a two-dimensional (2d) single particle model for the copolymerization of propylene-ethylene with heterogeneous ziegler-natta catalyst is developed. the model accounts for the effects of the initial shape of the catalyst and carck/ pore patterns on the copolymer composition, polymerization rate and the average molecular weight properties. the spherical and oblate ellipsoidal shapes of catalyst p...

Abstract Complex pore‐scale dynamics have been observed during multiphase flow through porous rocks. These are not incorporated in large scale models for the migration and trapping of subsurface fluids such as CO 2 or hydrogen. We show that fluctuations pressure measured at core‐scale (centimeters) can reflect fluid displacements (millimeters). The spectral characteristics data shown to depend ...
