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

A very simplified system for high voltage test is studied, considering reason for voltage holding failures which are not covered by conventional and local design criteria. A first understanding of the problem is obtained by solving the electrostatic potential in a 2D axis symmetric ... En savoir plus

This work is focused on Micropump optimization for drug delivery application. Diabetes is one of the widely pervaded diseases. Among the side effects of hyperglycemia is the weakness of the whole body, so the patient will be unable to inject manually the drug. Therefore, Micropumps are ... 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 ...

Solar systems are used around the world, especially in sunny and dry regions, to convert radiation energy from the sun into electricity or heat. Soiling, as dust deposition onto surfaces is commonly called, hinders this conversion of the solar energy by blocking of the incidenting light. ... En savoir plus

Modeling of fractured porous media systems is currently of high interest in various academic and applied fields, mainly in the geological and material sciences. The very different scales of the region of an application case on the larger end and the fracture on the lower end pose a ... En savoir plus

Electric field can bring liquid in motion and thus influence heat transfer. Electro-convection (EC) can be caused by electric forces acting on a liquid, even in absence of space charge. Here, we studied heat transfer in a metal vessel filled by oil, with a submersed high voltage ... En savoir plus

Transplantation of organs and tissues remains the solution for repair of damaged tissue, yet the shortage of donor human organs for transplant is another issue as well. In the field of regenerative medicine, several regenerative technologies have recently been developed using various ... En savoir plus

Organogenesis, the genesis of organs during embryonic development, is an active research field involving biologists, mathematicians and computational researchers. Fundamental questions of the formation of shape and the control of growth are still not answered. We focus on the development ... En savoir plus
