Today’s driver hardware for High-intensity discharge (HID) lamps is bulky, expensive and not particularly energy-efficient. A downscaling of the devices seems possible by increasing the operation frequency from typically 400 Hz to some hundred kilohertz. However, efforts to design high ... Per saperne di più
COMSOL Multiphysics® is being utilized to develop Thermal Model for Wire Directed Energy Deposition Additive Manufacturing (Wire-DED) process with an objective to analyse the heat transfer phenomenon during and after the process. Wire-DED process’s growing industrial acceptance at a very ... Per saperne di più
Plasma torches are used in processing of materials and in energy industry for producing plasma. In this work we use the Equilibrium DC Discharge physics interface of COMSOL Multiphysics® to model a DC non- transferred arc plasma torch, under hypothesis of local thermodynamic equilibrium. ...

Plasma torches are used in processing of materials and in energy industry for producing plasma. In a non-transferred arc plasma torch, an electric arc can be glowed by applying a direct current (DC) between the cathode and anode, both placed inside the torch. Then, the plasma (Fig. 1) is ...

High-intensity discharge lamps will in the foreseeable future be important light sources despite a growing market share of LEDs. Cost and energy efficient high frequency (300 kHz) operation is hampered by the excitation of acoustic resonances inside the arc tube, which results in low ... Per saperne di più
2D self-consistent nonequilibrium model of a free-burning arc in argon has been developed. The model is based on the COMSOL Multiphysics® platform and describes in a self-consistent manner the fluid dynamics, the heat transfer, the magneto-electrodynamics, and species conservation. The ...

In 2016 the group of experimentalists from the Institute of High Current Electronics (Tomsk, Russian Federation) have been discovered a novel phenomenon related to atmospheric plasma jets that was called an “apokamp” (originated from Greek words “off the bend”). This new plasma jet ... Per saperne di più
The purpose of this paper is to present a numerical modeling of plasma phenomena in beryllium emissions using COMSOL Multiphysics software. The Beryllium films were deposited on mirror polished fine grain graphite substrates using the Thermionic Vacuum Arc (TVA) technology available at ... Per saperne di più
Photovoltaic (PV) devices on its operational life are exposed to the action of environmental conditions, which can produce damage either chemically or mechanically. For this reason, traditional PV panels are made of different materials including glass, encapsulant, solar cells, backsheet ... Per saperne di più
최근의 수치모델링 연구들은 맨틀 플룸(mantle plume)이 배호(back-arc)지역의 분지 및 산맥(basin and range)과 유사한 지구조를 형성시키는 성인임을 제시하였다. 섭입 슬랩 후퇴(slab roll-back) 현상에 의해 지각에 가해지는 인장력과 지각 아래로부터 상승하는 뜨거운 맨틀 플룸으로 인한 지각 강도 감소가 더해져 배호 지역에 분지를 형성시킨다는 것이다. 이처럼 분지 형성 작용에 있어 맨틀 플룸의 역할이 중요해짐에 따라, 수치모델링의 필요성이 커지고 있기 때문에 초기 연구로써 ...
