[3] Fraunhofer Institute for Machine Tools and Forming Technology, Chemnitz, Germany

Precise electrochemical machining (PEM) is a non-conventional machining technology, based on anodic dissolution of metallic work-pieces. In this study an additional extension of the precise electrochemical machining with a precise angle-controlled cylinder positioning is aimed. Due to ... Read More

Two-Phase Flow Models of Gas Generation and Transport in Geological Formations

O. Silva [1]
[1] Amphos 21 Consulting S.L. - iMaGe Consortium, Barcelona, Spain

Gas generation and transport through porous media is a process common to many field applications such as radioactive waste and underground gas storage. In these operations, the gas phase evolution depends on the thermodynamic conditions at depth, the properties of the fluids (density, ... Read More

Hydrogen peroxide (H2O2) vapor is a preferred medium of sterilization in different fields of industry. Among the fact that it dissociates to oxygen and water (environmentally-friendly), H2O2 vapor possesses strong mircobicidal and sporicidal characteristics. As such, the use of H2O2 ... Read More

Model and App of Hydrophobic Meshes Used in Oil Spill Recovery

O. Silva [1], E. Coene [1], J. Molinero [1], B. Shafei [1]
[1] Amphos 21 Consulting S.L., Barcelona, Spain

Hydrophobic meshes are a new, promising technique for the recovery of spilled oil in the ocean. They allow to recover and store oil, while filtering it from the surrounding water. They are clean, efficient and can be used in continuously. These meshes have one drawback, however: if they ... Read More

Multiphysics Analysis of a 130 GHz Klystron
