空芯光纤因空气芯的存在，理论上具备极低的光学非线性、色散与极高的损伤阈值，同时能够大大减弱了光纤材料吸收的影响，适合极端波长、大功率激光以及超短脉冲传输，在光通信、传感、微加工以及气体非线性研究等领域具有极大潜力。其中，反谐振空芯光纤因其简单有效的结构设计及低损宽带传输的特点而备受关注。这里我们利用COMSOL的波动光学模块对其进行若干数值仿真来研究针对此类具有大芯径-波长比和稀疏精细结构微结构空芯光纤的网格划分策略，并基于此进一步研究了反谐振空芯光纤的结构参数对其泄漏损耗以及材料吸收所引发的材料损耗的影响。我们通过对空气 ... Mehr lesen
储氢合金的PCT曲线和氢化动力学性能是描述合金储氢性能的重要标准，目前对合金的PCT曲线测试一般采用体积法，对合金氢化反应动力学的研究一般采用等容差压法。但在实际生产过程中，储氢合金通常是在恒定氢气流速的情况下工作的，所以研究合金在恒定氢气流速条件下的吸氢动力学性能很有必要。与实验相比，采用数值模拟预报合金的吸放氢性能节省了大量的时间和成本，具有突出优势。目前金属Pd及其合金被广泛应用于储氢及氢气纯化等领域，我们通过COMSOL软件建模，构建Pd吸氢热力学与动力学特性模型，选用传热、流体流动、域常微分等物理场模块建立了Pd在恒定氢气流速下吸氢动力学的计算模型 ... Mehr lesen
