摘要

空心光子晶体光纤(HC PCFs)为快速响应光学气体传感提供了一种微尺度电池。本文对HC-PCFs中甲烷和氢气在环境压力和温度下的流动行为进行了计算模拟。建立了一个数学模型，研究了气体在不同结构和长度的HC-PCF中的扩散时间。结果显示了沿HC-PCF核心长度方向气体浓度随时间的变化关系。

Mathematical Modelling of Gas Flow in a Hollow Core Optical Fibre

Hollow-Core Photonic Crystal Fibres (HC PCFs) provide a microscale cell for fast response optical gas sensing. This paper presents a computational simulation of flow behaviour of methane and hydrogen gases in HC-PCFs under ambient pressure and temperature. A mathematical model has been developed to study the gas diffusion time in different structures and lengths of HC-PCF. The results show the relation of gas concentration over time along the length of HC-PCF’s core.
