基于磁流体动力学与Maxwell方程组，建立微束等离子弧焊电弧的二维轴对称模型，应用COMSOL软件进行求解计算，得到了微束等离子弧焊的电弧温度场、流场、电流密度、电弧所受洛伦兹力以及工件表面电弧压力分布情况，并通过实验所拍摄的电弧形态对模拟的温度场加以验证。结果表明微束等离子弧焊电弧温度、等离子体速度与电弧所受洛伦兹力具有相同的变化趋势，均从阴极到阳极先增大后减小，从电弧中心逐渐向四周降低，最大值出现在喷嘴内部中心区域；电弧电流密度在阴极下端面取得最大值，在工件上表面取得最小值，且从阴极到阳极减小速度呈一个先减小后增大再减小的趋势；电弧压力与等离子体流速径向变化相同 ...

High intensity discharge lamps can experience flickering and even destruction, when operated at high frequency alternating current. The cause of these problems has been identified as acoustic resonances inside the lamp’s are tube. Here, a finite element approach for the calculation ... Per saperne di più
Recently, the researchers usually use the hydrodynamic Drude model (HDM) to investigate the nonlocal optical response of metallic nanostructure. The advantage of the HDM is easy to implement numerical calculation for larger and more complex-shaped nanoplasmonic structures. For the HDM, ... Per saperne di più
Metamaterials are a new class of artificial materials, which possess various unusual properties. One of these properties is a negative index of refraction produced by setting both the dielectric permittivity ε and the magnetic permeability μ of the material less than zero. Unique ...

Cerebral vasospasm is a complication of subarachnoid hemorrhage and other neurosurgical emergencies that reduce blood flow to the brain. Part of the approach to management of vasospasm is to improve flow through the stenotic areas by reducing by decreasing blood viscosity and enhancing ... Per saperne di più
Inductively coupled plasmas (ICP) are largely used as a convenient way to produce large ion currents in industrial applications and for particle accelerators and for the Neutral Beam Injectors (NBI) envisioned for tokamak heating (ITER project and beyond). Among specifications we have ... Per saperne di più

He obtained the diploma as \"Ingénieur Physicien\" from the Ecole Polytechnique Fédéreale EPFL in Lausanne, Switzerland in 1979, and a PhD at the local ... Per saperne di più
COMSOL Multiphysics® can play a crucial role in jumpstarting undergraduate research programs in physics and engineering at colleges with limited financial support and small faculty size. The engineering physics program at Ramapo College of NJ has 48 majors and 4 full time faculty with ... Per saperne di più
High power Terahertz (THz) sources have become a topic of great interest for a wide variety of applications from medical science to security systems and from material science to telecommunication. The high output power of these THz sources mainly depends upon high current density and ... Per saperne di più
The ITER-ECE transmission lines consist of smooth-wall circular waveguides, including miter bends and other components. The performance of the TL is crucial to ensuring that the requirements for the diagnostic to measure the plasma parameters are met. COMSOL Multiphysics® has a finite ... Per saperne di più
