Foam layer structure on countercurrent contact elements with stabilization

Ultraefficient reduced model for countercurrent two-layer flows

Contact Impact Elements

Partant du continu pour arriver au discret, nous essayons d’éclairer les rôles joués par les différents composants participant de l’élaboration d’éléments numériques de contact en dynamique, dans le cadre des transformations mécaniques finies. Cette démarche permet, non seulement d’avoir un référent utile en cas de besoin d’adaptativité, mais également de retrouver en les consolidant, les éléme...

Countercurrent-distribution studies on histones.

1. The possibilities of fractionating histones and histone fractions by means of countercurrent distribution between two phases formed by water and butan-2-ol, in the presence of various concentrations of trichloroacetic acid, have been examined. 2. Although the principal histone fractions differ considerably in their partition ratios, a satisfactory resolution of the principal histone fraction...

Vibration and Noise Reduction Optimization Design of Mine Chute with Foam Aluminum Laminated Structure

The mining chute is an important equipment in the process of coal transportation and coal screening preparation. During the working process, the mining chute will generate a lot of vibration and noise because of constantly friction and impact of gangue and coal blocks. In order to reduce the vibration and noise during the operation of the chute, a new type of foam aluminum laminated structure i...

Structure of random monodisperse foam.

The Surface Evolver was used to calculate the equilibrium microstructure of random monodisperse soap froth, starting from Voronoi partitions of randomly packed spheres. The sphere packing has a strong influence on foam properties, such as E (surface free energy) and (average number of faces per cell). This means that random foams composed of equal-volume cells come in a range of structures ...
