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 ... Mehr lesen
Introduction: In recent years, metasurfaces have been demonstrated to control the phase and amplitude of light across a planar interface and implemented for optical functions such as beam-steering, focusing, and polarization rotation. Initial efforts using plasmonic-based scatterers ... Mehr lesen
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 ... Mehr lesen
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 ... Mehr lesen
In this paper, we examine changes of the electric field distributions in waveguide-based axial-type microwave plasma source (MPS) during tuning procedure. The distributions strongly depend on position of the movable short, so does the wave reflection coefficient of the incident wave. A ... Mehr lesen
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 ... Mehr lesen
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 ... Mehr lesen
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 ... Mehr lesen
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 ... Mehr lesen
We use COMSOL Multiphysics® for solving distributed optimal control of un- steady Burgers equation without constraints and with pointwise control constraints. Using the first order optimality conditions, we apply projection and semi-smooth Newton methods for solving the optimality ... Mehr lesen
