Materials with an order variable in thermal conductivity as a function of temperature are desirable for thermoelectric heat energy recovery, building thermal insulation and solar thermal applications. Thermal Conductivity is an inherent material property. Engineering the fundamental ... Per saperne di più
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 ... Per saperne di più
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 ... Per saperne di più
Additive manufacturing technologies do not share the same rendering depending on the type of material discontinuities induced by material processing. This study aims at revealing the role of microstructural defects as driving factors for the mechanical performance of polymeric parts ... Per saperne di più
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 ...

This paper describes the modeling of an electrochemical biosensor embedded in a microfluidic channel to determine the concentration of a target biomolecule. The total amount of analyte in the sample can be calculated by integrating the analyte concentration over the duration of the peak ... Per saperne di più
A Dutch firm manufactures a mounting system to fasten roof workmen to the roof of a flat roof building to prevent them from falling down from the roof. The system is mounted to the flat roof afterwards, i.e. after the completion of the thermal insulated roof. Because of the mechanical ... Per saperne di più
Cooling of high-power density electronic devices remains a challenge. Microfluidic heat-pipes with the potential of achieving ultra-high thermal conductivities offer a low-cost technology for cooling electronics. To achieve high thermal conductivity, it is critical to maximize the rate ... Per saperne di più
Navy systems, such as turbine engines, produce large quantities of thermal energy. This energy is a byproduct of the work produced by the engine during operation and is typically rejected to its surroundings. The temperature difference between the turbines and the ocean is substantial ... Per saperne di più
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 ... Per saperne di più
