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...

Aluminum foam has received considerable attention in various fields and is expected to be used as an engineering material owing to its high energy absorption properties and light weight. To improve the mechanical properties of aluminum foam, combining it with dense tubes, such as aluminum foam-filled tubes, was considered necessary. In this study, an aluminum foam-filled steel tube, which consi...

BACKGROUND The introduction of sclerotherapy using foam sclerosants has revitalized interest in this method of treating varicose veins. Foam is made from detergent-type sclerosants already established as safe and effective in conventional liquid sclerotherapy. OBJECTIVE European experts in foam sclerotherapy were invited to exchange their opinions and to work on consensus statements and recom...

With the increase in drilling fluid density requirements low-pressure coefficient formations, traditional hollow bead fluids and foam each have different degrees of deficiencies. Through extensive indoor experiments, an amphoteric surfactant (cocoamidopropyl betaine) with better foaming performance was selected to formulate ultra-low-density that combines a agent glass microbeads reduce fluid, ...

The objective of this manuscript is to study the possibility improving thermal performance an Evacuated Tube Solar Collector (ETSC) with integration a Phase Change Material (PCM) incorporated into metallic foam and fitted plate fins. A 2D mathematical model has been proposed. Two types metal foams (copper nickel) were inserted. In addition, effect pore size on heat transfer was studied. results...

Shan-Chen model is a numerical scheme to simulate multiphase fluid flows using Lattice Boltzmann approach. The original ShanChen model suffers from inability to accurately predict behavior of air bubbles interacting in a non-aqueous fluid. In the present study, we extended the Shan-Chen model to take the effect of the attraction-repulsion barriers among bubbles in to account. The proposed model...

objective(s):atherosclerosis is chronic inflammatory process triggered by oxidative stress. oxidative stress can increase hydrogen peroxide (h2o2)level, which induce atherosclerosis through the processes such as formation of perivascular adipose tissue (pvat), foam cells, and atherosclerotic plaque. antioxidant is needed to control negative effects of oxidative stress. one source of antioxidant...
