Surface-enhanced Raman scattering (SERS) is a fingerprint spectroscopy whose sensitivity is down to single molecule level. The mechanism of SERS is mainly contributed to huge enhancement of local electric field, which originated from surface plasmon resonance of metal nanostructures. It ... Read More
随着电力工业的快速发展，母线板作为汇集、分配和传送电能的装置，广泛应用于各个电工领域。由于流过母线板的电流一般较大，其温升发热问题不容忽视。该问题涉及电磁场、温度场、流场及位移场等多个物理场的综合。为了更好地研究其发热散热问题，本文采用 COMSOL Multiphysics® 多物理场直接耦合分析软件，基于有限元理论，在考虑设备几何形状和材料物理特性影响的基础上，对母线板进行三维建模。分别在瞬态和稳态情况下对母线板进行电—热—力耦合场分析，电—热—流耦合场分析，从而研究母线板的温度、电流密度分布规律和由于热膨胀引起的形变大小。最后加入层流，分析在考虑气流冷却效应时 ...

摘要 微通道换热器是一种高效换热设备，与普通换热器相比，微型换热器体积小，传热系数高，具有广泛的应用前景。微型换热器的实验研究存在较大的难度，而数值模拟则是深入研究微型换热器的重要方法。本文采用通用商用软件 comsol模拟了微型错流式换热器（MCHE）。 与传统换热器不同，微型换热器固体材料内部沿流体流动方向的热传导会显著地影响换热性能，而以往针对这方面研究是非常有限的。在本文中，通过数值模拟的方法研究了流速对MCHE温度场、压力场、换热系数、局部努塞尔数分布等的影响。 关键词：微型错流换热器，轴向导热，数值研究，总传热系数 Read More
