Wind tunnel distributed temperature sensing with actively heated fibers and microstructures for detecting wind direction

Wind tunnel tests were performed using distributed temperature sensing with actively heated fibers that had microstructures attached in opposing directions on neighboring fibers. These microstructures created a temperature difference between fibers that depended on wind speed, providing a prototype for distributed sensing of wind direction. These data are connected to a publication detailing this work and method, "Distributed observations of wind direction using microstructures attached to actively heated fiber-optic cables".

Data are stored in a netcdf format  and includes the instrument reported temperature ('instr_temp') and calibrated temperature ('cal_temp') with the various parameters tested in the linked paper available as coordinates, labeled along an 'expname' dimension.

The included ipython notebooks provide examples and explanations for using these laboratory data.

本研究采用搭载主动加热光纤的分布式温度传感系统开展风洞试验，相邻光纤上附着有方向相反的微结构。这些微结构可在光纤间产生与风速相关的温差，为风向分布式传感提供了原型方案。本数据集关联一篇详细阐述该研究工作与方法的学术论文，题为《基于附着微结构的主动加热光纤缆的风向分布式观测》（Distributed observations of wind direction using microstructures attached to actively heated fiber-optic cables）。

数据集以NetCDF（网络通用数据格式）格式存储，包含仪器上报温度（'instr_temp'）与校准后温度（'cal_temp'）；关联论文中测试的各类参数可作为坐标变量，沿'expname'（实验名称）维度进行标注。

随附的IPython笔记本（IPython Notebook）提供了该实验室数据集的使用示例与操作说明。
