This study examined an enhanced foam-flooding system incorporating nanoparticles and polymers under geological conditions of a reservoir the Shu 16 block in Yushulin oilfield. The is mainly comprised anionic foaming agent (CQS-1) nonionic surfactant (FH-1). We screened 17 foams by evaluating their volumes foam half-lives using Waring-blender dynamic analysis methods, were selected after examini...

milk-based espresso coffee is one of the most popular beverages. foam is an essential quality characteristic for this beverage. foam formation and stability is mainly related to the milk composition. in this study the influence of three different concentrations of xanthan gum (0.05, 0.1 and 0.2 g dm-3) and three different temperatures (50, 60 and 70 °c) on foam stability were examined and exper...

Foam fraction can be retrieved from space-based microwave radiometric data at frequencies from 1 to 37 GHz. The retrievals require modeling of ocean surface emissivity fully covered with sea foam. To model foam emissivity well, knowledge of foam properties, both mechanical and dielectric, is necessary because these control the radiative processes in foam. We present a physical description of fo...

The annular foam breaker is one which uses the vacuum and shear force generated by the Coanda effect to break foam. The pressure distribution directly affects its performance. So an investigation on the flow characteristics inside the annular foam breaker is important to optimize its structure. In this paper, the computational fluid dynamics (CFD) code, FLUENT, is employed to simulate the flow ...

In modern polymer composite technology, the use of waste products from other industries or processed is reasonable, but this requires more research. The purpose research presented in article was to develop a methodology for selecting composition modified polyethylene foam and assess flammability materials obtained. these studies, content recycled polyethylene, as result solving optimization pro...

This article summarizes the state-of-the-art knowledge gained from field observations and laboratory studies regarding foam as a liquid controlling agent in porous media. Being least explored property of foam, its effect potential have often been overlooked or simply ignored. The aim with this review is therefore to demonstrate abilities that could block, reduce, delay, suppress, divert water f...

Carbon foams have gained significant attention due to their tuneable properties that enable a wide range of applications including catalysis, energy storage and wastewater treatment. Novel synthesis pathways novel via yielding complex, hierarchical material structure. In this work, activated carbon (ACFs) were produced from waste polyurethane elastomer templates using different pathways, one-st...
