1. Introduction Current rapid prototyping techniques are of limited use in the early phases of design. In order to establish a more dynamic and effective means, the concept of augmented prototyping recently gained interest [Stork et al., 2002][Verlinden et al., 2003]. The concept of Augmented Prototyping combines Rapid Prototyping techniques to obtain 3D physical objects (e.g. Stereo lithograph...

reaction to fire of fire-retarded rigid pur foams and two types of metal faced rigid polyurethane foam core sandwich panel was evaluated by using cone calorimeter test method. the tests were carried out in various radiative heat fluxes from 15 to 75 kw/m2. the radiation rate effect on reaction to fire parameters, including time to ignition (tti), peak of heat release rate (prhr), total heat rel...

Liquid foams have important practical applications in mineral separation and oil recovery. However, the details of the foam mechanics in these applications are poorly understood. Foam scientists have used 2D foam simulations to model foam behavior and 2D visualization solutions have helped them explore and analyze their data. Three-dimensional foam simulations remove some of the simplifying ass...

Collapse of liquid films in a foam is characteristic compared to that individual films. The mechanism and physical conditions collective bubble collapse which directly contribute stability have been clarified.

The main objective of this research is to manufacture expanded perlite (EP) foam-filled stainless steel tubes for energy absorption application and investigate their physical compressive behavior. Foam-filled (FFT) were manufactured by consolidating perlite/sodium silicate composite foam inside the tube. EP particles size 5-6 mm taken manufacturing FFTs. Two different sodium solution water (S/W...

The effect of yeast strain and aging time on the chemical composition, analytical, and sensory foam properties of sparkling ciders has been studied. The analytical foam parameters (foamability, HM; Bikerman coefficient, sigma; and foam stability time, T(s)) were significantly influenced by aging and yeast strain. The sensory attributes (initial foam, foam area persistence, bubble size, foam col...
