Cogging torque in permanent magnet motors and generators is characterized by a torque ripple. These torque fluctuations cause vibrations, noise and speed fluctuations. This paper presents finite element (FE) analyses results that show a previously unaddressed low frequency modulation of ... Per saperne di più
Engineering design has long been dominated by orthogonal Cartesian principles. Nature inspired equation based mathematical surfaces are under renewed interest due to their innovative design potential and practical viability by 3D printing. In this paper, the parametric surface ... Per saperne di più
复合型电磁轨道发射装置是轨道型电磁发射器研究的一个重要方向，复合型轨道是对轨道的内表面添加保护层，由于电磁轨道在发射时存在复杂的热量变换，轨道表面材料在吸收这些热量之后会发生脱落、气化甚至是电离等现象。为减弱在发射过程中的烧蚀现象，在轨道的表面添加保护层，使轨道内表面材料具有强的耐热性能，并且强度、韧性较好。运用 COMSOL Multiphysics® 软件仿真模拟复合轨道在发射过程中的温度、电流、应力和应变的变化。 Per saperne di più
In Mexico there is a decline in the production of oil deposits due to the lack of effective treatment of oil emulsions, which generate a problem in the reinjection of emulsified water, transport of oil with high water content and corrosion in the oil refineries. Through the simulation ... Per saperne di più
Optical tweezers work on the idea of non-contact Optical Pressure felt by transparent particles, when shined by coherent light source such as lasers. On the other hand when light falls on the metal it excites the electron inside it and make them free. When these free electron cloud ... Per saperne di più
Introduction: Flat lenses require precise control of a phase gradient across an interface, which is enabled through the application of engineered surfaces, such as Metasurfaces [1]. Periodic arrays of plasmonic antennas have been utilized to generate this desired phase gradient, which ... Per saperne di più
This work presents the analysis of a wireless power transfer system consisting of two coupled coils and ferrite slabs acting as flux concentrators. The study makes use of Finite Element Method (FEM) simulations to predict the key performance indicators of the system such as coupling, ... Per saperne di più
In this paper resonances in tapered double-port TEM waveguides are used as benchmark for simulations. FEM simulations with COMSOL Multiphysics® and simulations using generalised telegraphist's equations with MATLAB® are compared to ananalytical method capable of calculating the ... Per saperne di più
The specular and diffuse reflection properties of sunlight at the rear surface of silicon solar cells with various degrees of roughness are computed by solving the Maxwell and material equations in two dimensions, using the COMSOL RF Module. The model is tested on planar Si/SiO2/air ... Per saperne di più
An optimal control problem (OCP) is studied to a PDE of elliptic type as well as state constraints. The resulting optimality system contains two PDEs, one algebraic equation and the so called complementary slackness conditions, i.e. dual products between function spaces. At this point, ...
