Additive manufacturing gathers technologies where near net shape components are produced by depositing successive layers of materials. Among these technologies, the Layer Beam Melting (LBM) process – often referred to as Selective Laser Melting (SLM) – is garnering industrial interest, ... En savoir plus
INTRODUCTION: The Dirac equation is employed in particle physics and historically gave the first combined unification of quantum mechanics and relativity theory by introducing a four component wave function Ψi. This wave function described the behavior of fermion type particles (e.g. ... En savoir plus
In this paper, detail magnetostructural analysis of fusion grade superconducting toroidal field coils that are used in ‘tokamaks’ is presented. The stresses that arise due to Lorentz forces in large size superconducting coils that carry high currents are of catastrophic type in nature. ... En savoir plus
我国南海地区常年高温高湿、雨量充沛、太阳辐照强度大,风速大且风中包含大量水汽,处于多强场耦合的热带海洋环境下,建筑围护结构承受着远高于大陆地区的热湿压力。尽管我国已开始对南海地区进行开发建设,但尚无相应的建筑热工设计指标体系进行指导,使得热工选材无据可依,围护结构设计有所失真。作为指标体系建立的重要基础研究工作,探究极端热湿气候下围护结构热湿耦合传递特点具有重要的科学价值和实际意义。本文针对南海地区建立了一维瞬态热湿耦合传递模型,利用Comsol数学模块系数型PDE接口进行了求解,探讨了热量传递、水分传输过程中相关参数的变化特点 ... En savoir plus
COMSOL Multiphysics software, when properly configured, can readily solve modeling problems in the laminar flow regime using the standard Navier-Stokes equations or in the fully turbulent flow regime using the kappa-epsilon model. Failure to solve a particular model is typically ... En savoir plus
Insulin released by the beta-cells of pancreatic islets is the main regulator of glucose homeostasis, hence, insulin secretion models are of considerable interest for many possible applications. Building on our previous oxygen consumption and cell viability model for avascular islets of ... En savoir plus
The biological hair-cell is a modular building block of a rich variety of biological sensors. These sensors are responsive to various mechanical properties like vibration, touch, gravitational forces, etc., especially flow. Using micro and nano-fabrication technology, an engineering ...

Laser-based powder bed fusion (LPBF) is a promising additive manufacturing technology, where metallic parts are produced in a layer-wise manner. At each step, a rapid-moving laser irradiates and subsequently melts predefined zones of a relatively thin layer of fine spherical metal ... En savoir plus
城市内超高层建筑物的高度和密度的快速增加会影响城市风环境,城市风环境与人身健康、社会经济息息相关,然而目前缺乏针对超高层建筑物的高度和密度对风环境影响的定量研究。本文利用COMSOL Multiphysics® 5.2版本CFD模块中的湍流k-ε接口,采取控制变量法,数值模拟超高层建筑物不同高度和密度分别对应的城市风场,从高空风噪、阻挡作用、城市通风三个方面综合评价风环境质量,探索形成良好风环境的高度密度参数组合。研究结果表明,相邻两栋超高楼之间的高宽比小于0.89时,高空风噪、阻挡作用、城市通风都能较好地符合环境要求。 En savoir plus
The U.S. Naval Academy has used COMSOL as a research tool for many years. Academic usage of COMSOL for student use has only begun in the last five years. Student involvement comes in four types, course-wide usage, focused course related work, student projects and semester-long research ... En savoir plus
