A better understanding for wet snow is essential for snow pack stability, the effect of water percolation and friction between ski and wet snow surface. Technical details about ... Per saperne di più
飞行器遭受雷击时会产生多物理效应，包括电磁感应效应、热效应和电磁力效应等。建立三维电磁、电磁-热耦合、电磁-热-力耦合等多种典型模型进行仿真分析，通过对电势、电流、温度、电磁场和力等物理量的分析，研究飞机附着点、雷电防护布局、雷电流分布、金属网/复合材料熔蚀、机舱内电磁场分布、油箱缝隙打火、结构受力等问题。仿真结果在不同程度上可以为飞行器的雷电防护提供重要参考和设计依据。本文以 COMSOL Multiphysics® 多物理场耦合软件为仿真分析工具，建立多种典型问题模型进行计算并对结果分析，说明雷电及其相关问题可以通过仿真分析进行评估和解决。 Per saperne di più
Plasma torches are used in processing of materials as well as in the energy industry for producing plasma. In a non-transferred arc plasma torch, an electric arc can be initiated by applying a direct current (DC) between the cathode and anode, both placed inside the torch. Then, the ... Per saperne di più
Optical cloaking was considered as fictional. Recent developments shows that macro scale optical cloaking is practical and functional. Brief review of ray optics based macro optical cloaking concepts are given. COMSOL Multiphysics® software simulations of cloaking devices are detailed. ... Per saperne di più
The calculation of additional losses in induction machines is a challenging task. In skewed motors, a part of these losses is connected to the phenomena of inter-bar currents. Inter-bar currents flow between adjacent bars through the rotor lamination. Since they are aligned perpendicular ... Per saperne di più
