Foam flooding (or injection of foam) is a common technology to enhance oil recovery. Although the effects of permeability on foam flooding were well studied in many laboratory experiments, little research has been focused on the specificity of low permeability. In this paper, a series of constant-quality nitrogen foam flow experiments were conducted to investigate the effects of permeability on...
We studied the flame propagation and combustion properties of a lightweight fibrous foam produced from a layered double hydroxides (LDH) modified thermomechanical pulp fibres. The in situ synthesis of Mg-Al LDH with pulp fibres was engineered to include both micron and nano-sized particles. The method allowed loading the fibres with LDH up to 34% (w/w). Observed pyrolytic effects included 60% r...
Abstract Background Soft, biological, and bio-inspired materials are often compositionally heterogeneous structurally anisotropic, they frequently feature graded or layered organizations. This design complexity enables exceptional ranges in properties performance yet complicates a fundamental understanding of the contact mechanics. Recent studies soft gel layers have relied on Hertzian Winkler ...
An unsteady-state, fugacity-based, indoor chemical fate model was developed to explore kinetic resistance of multilayer of polyurethane foam (PUF) commonly found in upholstered furniture. The Dynamic Layered PUF Simplified Multimedia Indoor Model (DLP-sMIM) was based on the Multimedia Indoor Model created by Zhang et al. (Zhang, Diamond et al. 2009). DLP-sMIM was applied to real and hypothetica...
