In this paper, a numerical study is conducted on the melting and solidification process of metal foam/paraffin wax with cyclic heating and cooling. A mathematical model based on the Brinkman-Frochheimer extended Darcy equation and the local thermal non-equilibrium model (LTNE) is ... En savoir plus
For automotive applications, simulations are used to optimize the position and orientation of a subwoofer (loudspeaker) in a very constrained space to get the best acoustic performances. One solution is to use particular part of the BIW volume as the subwoofer enclosure. The acoustical ... En savoir plus
Advancements in simulation technology are supported by rapidly evolving enablers such as Cloud infrastructure, high-performance computing platforms (on & off-premises), on-demand Machine Learning systems, and secure multi-user environments. These advancements provide an opportunity ... En savoir plus
We present a Finite Element Method simulation procedure that allows rapid development of prototype devices comprising novel self-referenced interference SPR (surface plasmon resonance) biosensing microstructures. The procedure takes advantage of COMSOL Multiphysics and MATLAB software ... En savoir plus
Current trends of research aims at the reduction of conventional fossil fuel consumption so as to mitigate anthropogenic global warming and thus to combat with the climate change. This can be done by shifting to more efficient, alternate, non-conventional and environmental friendly ... En savoir plus
In this work, electrothermal microgrippers designed using topology optimization are modeled. The microgrippers are composed of two 5 μm-thick polysilicon actuators facing each other. The gap between the actuators are 2 μm in the initial state and the microgrippers are able to both fully ... En savoir plus
当前普遍应用空调均是通过调控整个房间的温度来控制环境，因此难以解决人与人之间热需求不同的问题。由此新兴的个人通风系统通过仅针对性地调节人体周围的微环境来达到节能和使人体热舒适的双重目的。本研究即是通过COMSOL模拟来探究不同的顶板风口入风条件对于其正下方的坐姿人体热舒适程度的影响，从而对今后智能空调的设计提供一种思路。 在COMSOL软件中，一个人体模型以差集的形式被设置于一个443(m)的房间中，房间顶板正中心设置一个圆环形状的入风口，在房间一侧面的底部设置了一个狭长出风口。模型采用了流体传热和Realizable k-e两个模块，基于房间的对称性 ... En savoir plus
Ground-coupled heat pumps (GCHP) are successfully installed since at about 20 years in many countries to fulfill space conditioning requirements in building applications. In most cases the heat pump is connected to a system of vertical ground heat exchangers (as illustrated in Figure 1) ... En savoir plus
Polymer sheets are widely used for glazing and roofing structural applications. The primary design requirements of these polymeric sheets are to resist uniformly distributed wind loading. Conventional building materials such as steel and glass plates are relative stiffer compared to ... En savoir plus
Ground Heat Exchangers (GHXs) are rarely installed horizontally in linked ground source heat pumps used for space conditioning, because their energetic performance is lower than in the vertical solution. However, the horizontal one holds several advantages: it is easy to carry out and ... En savoir plus
