Fixed nitrogen is used in many forms ranging from nitric acid to hydrogen cyanide and is used as such for industrial applications. The reactions to produce these products are highly endothermic and favored by high-temperature processing. The most basic route of chemically fixing nitrogen ... Per saperne di più
Large-area, light-weight electromagnetic protection (EP) structures are needed to protect sensitive microwave sensors and communications systems from high-power microwave (HPM) and electromagnetic pulse (EMP) threats. This paper presents the use of COMSOL Multiphysics® for ... Per saperne di più
本研究基于COMSOL Multiphysics多物理场仿真平台，利用等离子体模块构建了等尺寸二维自洽流体模型，结合实验深入探究了辅助脉冲电压（APV）对大气压等离子体射流（APPJ）中电离波传播动力学特性的调控机理。仿真工作复现并深入了先前实验研究的关键发现，模型模拟了在辅助电极（AE）上施加不同幅值的APV时，电离波传播路径上的电势分布、电子/离子密度、电场强度及电子温度的时空演化过程。计算结果表明，电离波的产生影响了管外电势的产生与再分布，同时外加APV通过显著改变电离波前端的电势分布，从而有效调控其传播行为。模型与实验证明 ... Per saperne di più
Chipmakers widely use the plasma-enhanced chemical vapour deposition (PECVD) technique for depositing thin dielectric or conducting films on wafers. The primary objective for a deposition process is to have a good flow and species uniformity on the wafer. Typically, a carefully designed ... Per saperne di più
A lot of techniques are developed to treat soils polluted by hydrocarbons pollutants: incineration, thermal treatment, extraction, chemical oxidation, bioremediation… Some of these techniques are very energy consuming (incineration, thermal treatment…) and often need a subsequent ...

System for in-situ control of the ion angular distribution function (IADF) in plasma reactor is modeled. Typical IADF depends on the pressure, bias and excitation frequency. It is formed due to a difference in the physical properties of the plasma and sheath domains. The IADF is modified ... Per saperne di più
The electron beam emitted backward by Plasma Focus devices is being investigated as a radiation source for IORT (Intra-Operative Radiation Therapy) applications. A Plasma Focus device is being developed to this aim. The electron beam is driven through an electron pipe made of stainless ... Per saperne di più
High-intensity discharge (HID) lamps are energy-efficient light sources with excellent color qualities. A three-dimensional model of a low-wattage lamp, which includes plasma, electrodes, and burner walls, was developed in COMSOL Multiphysics®. Most parameters appearing in the coupled ...

Hemodialysis catheter lumens are routinely locked with heparin solution to reduce the risk of intra-luminal thrombus formation between treatment sessions. The lock volume infused is chosen to be the volume of the lumen, assuming no significant fraction of the heparin dose reaches the ... Per saperne di più
Enzyme reactions, blood flow and diffusion in human vasculature play interacting and fundamental roles in blood coagulation. In this complex mechanism, the balance between blood and clot is a delicate equilibrium, whose tight regulation is vital to avoid pathologies such as bleeding and ... Per saperne di più
