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...

Background and Aims: The quality of platelets (PLT) during storage is influenced by various factors. The purpose of this study was to determine the potential effects of the air bubbles and foam in the bag of platelet and its effects on the quality of the final product. Materials and Methods: In this paired-study, the air bubbles and foam, which develops after the preparation of the platelet un...

A variety of polymers or surfactant mixtures or aeration of a number of liquids could generate mixtures of liquid and foam. Therefore, characterizing the properties of liquid/foam mixtures has important applications in the chemical process industry. The lack of a robust automated method for characterization within limited time and with high accuracy, however, has made this task difficult. In th...

shampoos are products which remove surface grease and dirt from the hair shaft and scalp. the cleansing or detergent action of a shampoo is a primary function. however, the foaming characteristic of a shampoo has an important role in its acceptability. often alkanolamides are used for the formation of a stable foam; but because of producing nitrosamines, they are potentially carcinogenic compou...

proteins are not only considered as a nutritional source but also are responsible for a number of functional properties such as solubility, emulsification, foaming capacity and gel formation in food products. however, insolubility of the proteins (as can be seen in gluten) and therefore their insufficient functional properties have created some limita-tions for their incorporation in formulated...

Abstract: Enhanced foam flooding is a chemical flooding technology, which is applied to improve the recovery efficiency of oil and gas. The oil displacement agent of enhanced foam flooding is a foam that the polymer and surfactant solution as liquid. In this paper, three-dimensional mathematical model of unsteady flow is established about enhanced foam system in the porous media, and the numeri...

Liquid foams have important practical applications. To analyze the dependence of foam behavior on material properties, and to improve foam models, foam scientists work with dozens of related simulations obtained by varying these material properties as well as parameters such as foam attributes, properties of objects interacting with foam or shape of foam containers. We present visualization sol...

Foam dynamics is gaining interests within Computational Fluid Dynamics and Computer Graphics. We believe that liquid foam, or froth, is the next evolution in the field of fluid dynamics. Froth is the natural phenomenon of bubbles that arise due to nucleation of gas in liquids. As the physics of foams in two dimensions is better understood this thesis begins the journey of physics-based foam dyn...

This investigation presents the effect of various parameters on foam stability and its rheological properties. The underlying idea of this experiment is generating of drilling foam with uniform bubbles. The main problem of foam using is controlling its stability during field application. The most important parameters which cause Instability in foam are gravity drainage, gas diffusion and bubble...
