For certain classes of scientific and technical computations the cloud may offer easily accessible, scalable, and affordable gigantic computing power. A power that for these classes may lead to a step change in model and analysis complexity compared to what is feasible with dedicated clusters and similar networked solutions. Acoustics with or without interaction with coupled physics fields ...

The Automotive industry has now become a technology of “Drive by Wire”. This technology is used to replace the conventional mechanical system by electromechanical system which is able to perform the same tasks faster, more reliably and accurately. The problems with the traditional braking systems are unreliable at high speeds, long respond time, more brake pad wear, high temperature operating ...

A novel propellant technology requires extruding two formulations with differential burning rates together as a multilayered propellant. This propellant is processed into a concentric cylinder configuration, in the form of slow-fast-slow with single perforation. The material uses different path lengths between the inner and outer sections of the die, both coming from the same pressure driven ...

Greenhouse gases trap heat and make the planet warmer. The main greenhouse gases emitted by human activities are: Carbon dioxide (CO2). The use of fossil fuel is the primary source of CO2 [1, 2]. Accordingly, there is a need for an efficient and novel separation processes for removal of carbon dioxide from gas streams [3, 4]. Here, a flat sheet membrane contactor is used to remove carbon ...

The Ray Tracing Module in COMSOL Multiphysics® is used to setup and simulate a lens and compare the longitudinal spherical aberration (LSA) with the third order theory in optics. Some Seidel coefficients will be investigated and the geometry or solver settings will be discussed. Also a lens design will be shown in the presentation in which the front and back surface are optimized according the ...
利用 COMSOL Multiphysics® 软件中流体传热接口、层流接口、化学反应接口对 HVPE 法单晶生长过程进行模拟。建立了基于 HVPE 生长室内部结构的简单二维模型，并进行了标准的网格剖分，通过物理场耦合，并添加了生长过程中所需的生长气氛，研究了 HVPE 法进行 GaN 单晶生长过程中衬底表面厚度分布的变化规律。通过模拟结果发现，衬底表面存在显著的边缘效应，边缘处厚度显著高于衬底表面其它区域。

In many dynamical systems the behavior can be changed or even optimized by a suitably chosen external parameter. However, the complexity of the dynamics grows significantly if coupled systems are considered. As an example we examine the coupled dynamics of cancer cells and healthy cells during fractionated radiation therapy. In this method the iterative sequence of radiation and breaks leads to ...

Magnetic nanoparticles have diverse applications ranging from contamination control to medical diagnosis and treatment. Small airborne particulate matter (PM) is known to have adverse impacts to human health,, due to its high mobility when penetrating human respiratory systems [1,2,3]. Airborne PM consists of a multitude of chemical components [4,5], many of which are paramagnetic and ...

The mitral valve apparatus is a complex and refined mechanism located between the left atrium and the left ventricle of the heart which can manifest various kinds of pathologies. In order to support identification of potentially critical conditions resulting from some typical cardiosurgery operations, it is important to develop models of the mitral valve that enable prediction of both stress in ...
