As minimally invasive and robotic surgical devices get smaller, designing precise energy delivery to create the desired tissue effect becomes a key component in product development. With many interdependent physical phenomena occurring simultaneously, it becomes necessary to use tools ... Per saperne di più
Recently a lot of research efforts have been focused on using plasmonics and nanophotonic structures for enhancing emission processes ranging from lasing to single-photon generation. The design of such structures heavily relies on the insight obtained from numerical simulations. In this ... Per saperne di più
Solar cooling systems based on evaporation and absorption processes have been actively studied and different mechanisms based on various refrigerants are designed and developed. Amongst these systems, a single-stage close cycle design utilizing lithium bromide salt and water (LiBr-H2O) ... Per saperne di più
Pyrometallurgical furnaces are used to produce metals such as copper, nickel and platinum by the smelting process. During smelting, the undesired material components are separated from the desired metal resulting in the formation of a slag and matte/metal phase. The slag phase ... Per saperne di più
Microstructure evolution simulations using the kinetic Monte Carlo algorithm and the phase field method are routinely used to model and simulate sintering and densification of ceramic and metallic materials. Understanding evolution of microstructural features is important as these are ... Per saperne di più
Finite element method (FEM)-based solutions are known to contains errors and uncertainties due to at least four mathematical (M) and four physical (P) sources, namely, (M-1) mesh density or degrees of freedom, (M-2) mesh element types, (M-3) mesh quality such as mean aspect ratio, (M-4) ...

Most of existing material representations [1], even including the dynamic hysteresis and iron losses [2], ignore local microscopic non-uniformities. These concern the magnetic structure (domains and walls [3]) and are mainly due to surface effects, anisotropy and exchange [4]. One ... Per saperne di più
The most common cause of lithium ion battery failure is high temperature. Improper thermal management strategies can contribute to the temperature related premature battery failure. Excessive heat significantly impacts the performance, safety and cycle lifetime of the lithium ion ... Per saperne di più
扬声器的失真问题一直受电声业界的关注，尤其是谐波失真，它是影响扬声器重放声音音质的主要因素之一。 本文提出了一种基于 COMSOL Multiphysics® 软件预测扬声器谐波失真的仿真分析方法。该方法需建立包括磁场、振动系统和声场等多个物理场的扬声器的全模型，给扬声器加载一单频电压信号，用瞬态分析的方法可求解得到该频率激励下的扬声器的多个重要物理量随时间的变化函数，如流经音圈的电流I(t)、音圈的受力F(t)、振动系统表面上任意点的位移x(t)，以及声场中任意点的声压P(t)等。给扬声器加载一个时间长度为0.1s的单频电压信号，仿真分析所得的防尘帽顶点的位移曲线 ...
