Linear Induction Motor (LIM) has been identified as a key element for electromagnetic launching technology. The stator part of the motor when energized induces a linearly moving magnetic field which consequently produces a thrust force on the rotor part of the motor. Thus it accelerates ...

钨丝是早期热发射电子源阴极灯丝的关键材料，工程组件上多数采用的灯丝直径为0.127~0.203mm，一般将其制成V型发叉式。模型构建了三维灯丝几何结构，计算过程中对灯丝弯折角处的区域进行网格加密处理。结合COMSOL Multiphysics多物理场的电磁热模块，实现了对钨灯丝的温度分布模拟计算，并进一步计算不同几何结构和不同灯丝材料对灯丝温度分布的影响。仿真结果表明，在材料钨、钛、锆以及各种弯折角度下，灯丝最高温度与弯曲处温度差稳定在30~40K左右。从趋势上看，弯折角度α越小灯丝总温度越高。该工作解释了常见灯丝熔断点非灯丝针尖的工程问题 ... Per saperne di più

This Paper presents the results of a FEM simulation with Comsol Multiphysics for an Axial Flux Permanent Magnet Machine (AFPM) and compares them with analytic calculation methods (Matlab, Siemens Star-CCM Suite) as well as test bench measurements of a manufactured protype. The machine is ... Per saperne di più
The Z-pinch (or zeta pinch) is a type of plasma confinement system used in fusion power research. It relies on an electric current discharge within the plasma to generate a magnetic field that compresses the plasma, creating conditions conducive to nuclear fusion. The concept of Z-pinch ...

This study focuses on the design and optimization of a logging while drilling (LWD) tool with look-ahead detection capabilities, which is widely used in measuring formation resistivity and detecting formation boundaries ahead of the drill bit during oil and gas drilling operations. The ... Per saperne di più
Effectively storing hydrogen in solid form using metal hydrides requires careful attention to thermal management challenges due to the exothermic nature of hydrogen absorption in metal hydrides [1], [2]. The generated heat during this process must be efficiently removed to achieve ... Per saperne di più
