同轴磁齿轮是将一个或一组永磁体或电磁体安置在圆形转轴外侧，通过扭矩-速度的调整实现外部非接触式动能控制的机构，用于工业自动化控制和可再生能源等应用中，和机械齿轮不同，磁齿轮工作时无摩擦，所以能量损耗小。本文以二维旋转动网格模型为基础，在径向方向分别安置单个和多个永磁体。探究不同安置数量对外部空间环境产生的电磁感应规律。 Read More
Plasma reactors can be applied to the conversion of waste, biomass and fuels to synthesis gas (mixture of hydrogen and carbon dioxide) with efficiencies as higher as 90-95% and low energy demand, depending on the design optimization. In this work, a multi-step approach was applied to the ... Read More
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 ...

前期研究中，我们设计了基于准同轴结构的微波等离子体无极灯 [1]。该结构以激发后的等离子体作为同轴内导体，法拉第笼作为外导体。仿真结果显示，电磁波在等离子体 - 金属构成的准同轴波导中传播时，同步被等离子体吸收并形成驻波；实验中，激发后的无极灯呈现亮 - 灭周期性特征，这与仿真所得电子密度分布特性高度一致。 基于上述研究基础，结合激发后等离子体具备高电导率、可作为同轴内导体的特性，我们进一步提出新设计，一种用于在放电管中产生长等离子体源的装置。该装置采用矩形波导与同轴波导组合结构，仍以高电导率的激发后等离子体为同轴内导体，外导体则由金属壁构成。对 Ar ... Read More

为深入探究材料属性对电弧等离子体热力学特性的影响，本研究以反应烧结碳化硅（RB-SiC）陶瓷为研究对象，基于 COMSOL Multiphysics 建立了耦合电流、磁场、层流及流体传热的磁流体动力学模型，并与304不锈钢进行对比分析。该模型综合考虑了电流、磁场与流场之间的能量转换，以及等离子体对电极与工件的热量传递，能够较为准确地描述电弧等离子体特性。结果表明，相较于304不锈钢，RB-SiC 等离子体具有更高的温度和热通量，但由于其极高的导热系数，工件在击穿后能迅速达到热平衡，且最终温度显著低于不锈钢。同时，RB-SiC 的等离子体最高温度位置不随脉宽变化 ... Read More
