Carbon fiber as filaments or as continuously reinforced composite finds application in the electronic packages, electric vehicles, and electrical machines, owing to its excellent electromagnetic (EMI) shielding and high conductivity. Carbon fiber being good conductor of electricity (in ... En savoir plus

Plasma torches are used in processing of materials as well as in the energy industry for producing plasma. In a non-transferred arc plasma torch, an electric arc can be initiated by applying a direct current (DC) between the cathode and anode, both placed inside the torch. Then, the ... En savoir plus

This paper presents the design and simulation of micromixer for Lab-On-Chip (LOC) applications. There are two types of micromixers: one is an active micromixer and another one is a passive micromixer. This paper investigates microfluidic flow characterization and mixing rate of two ...

In electrochemical machining process, it is very important to control electrolyte flow field to remove contamination such as slug, or gas to be generated by the machining process as well as heat control for electrolyte, machining tool and work piece. To reduce the overcut of workpiece, ... En savoir plus

Small-scale plasma jets in atmospheric air can produce regions of highly reactive chemistry coincident with temperatures approaching room temperature allowing his type of cold plasma jet to be used for decontamination of surfaces and sterilization of living tissue. In the device under ... En savoir plus

Thomas Herrmannsdörfer got his PhD in experimental physics from the University of Bayreuth in 1994. In 1995, he received the Research Award of the Emil-Warburg-Foundation while he worked at the DFG-Graduiertenkolleg Bayreuth. From 1995 – 1998 he worked as a scientist at Hahn-Meitner ...

The finite element method applied to the k-epsilon turbulence model is used to investigate the two-stream turbulent mixing layer. Whereas the model is known as one of the most popular of the turbulence models to date, the model has yet to be applied to the classical mixing layer problem ... En savoir plus

The structural design of temporary storage facilities for radioactive waste generally requires the fulfillment of highly severe performance criteria if compared to conventional buildings. This work focuses on the study of the behavior of a steel door subject to the impact of extreme wind ... En savoir plus

The quality of coatings obtained by means of thermal spraying depends strongly on the mechanism of the interaction between the molten droplets and the surface to be covered. The aim of the present study is to simulate the impact of a droplet onto a substrate, in order to have a good ... En savoir plus

The U.S. Army Engineer Research and Development Center (ERDC) is currently exploring the use of infrasound sensors to monitor the health of structures of interest. Infrasound is acoustic energy below 20 Hz and is capable of propagating many kilometers from the source with little ... En savoir plus
