Ar/H2 discharges are frequently used in various industrial applications, such as etching processes, surface treatment, and film deposition. In the discharges, the active species, such as ions and hydrogen atoms, are responsible for surface reactions, which could be considered as the ... Per saperne di più
Two-dimensional plasma transport model was developed in COMSOL Multiphysics Plasma Module to investigate fundamental issues in ceramic metal halide (CMH) lamps starting using Ar/Hg penning gas mixture. The intent of this work is to provide insight into possible design rules that might be ... Per saperne di più
Our group developed an experimental millimetric capsule intended to release chemicals or drugs. The delivery mechanism of such device relies on the thermal expansion of carbon-elastomer composites which deform upon irradiation of light supplied by a Laser diode through an optical fiber. ...

Within this study a model of a single discharge of micro scale EDM was developed in accordance with Schulze et al [1]. The specific computation of the growth of the plasma channel has been derived from this literature. Applying COMSOL Multiphysics® a pseudo 3-D geometry was created based ... Per saperne di più
HIIPER is an experimental space propulsion device using a helicon and an IEC as a plasma generation and acceleration stage, respectively. There is an experiment in progress, but for true rapid iteration and to model the performance of the engine, COMSOL is a strong candidate for ... Per saperne di più
The discharge properties in low pressure inductively coupled Ar/CH4 plasmas operating at an RF frequency of 13.56 MHz and total gas pressure of 20 mTorr are studied in this work. The calculation of gas flow is performed in coupling with the plasma simulation. The gas flow rate is varied ... Per saperne di più
