The research presented here focuses on the development of a 3D printed wind tunnel and the relevant equipment to be used for calibrating bi-directional velocity probes (BDVP). BDVP are equipment to be used for measuring velocity flow by determining the pressure difference of hot gases generated during fires. The manufactured probes require calibration to determine the calibration factor to achieve precise measurement. The calibration is usually performed in wind tunnels which can be difficult to access due to costs, complexity and the various pieces of equipment required. The aim of the current study is to develop and assemble an inexpensive and easy-to-build bench-scale wind tunnel, with a data-logging system and fan control functionalities for fast and effective calibration of BDVP. A 3D printer with a PET-G filament is used, able to produce parts for the wind tunnel system which are durable and easy to handle and assemble. The system additionally includes an Arduino-based measuring unit with a hot-wire anemometer and temperature correction: Rev. P. This takes precise measurements; continuously logging data on a computer through a USB interface and capable of saving data on an SD card. This design provides users with parameters of velocity flow up to 4 m/s with standard deviation of 1.2 % and turbulence intensity of 1 %. The main advantages of this wind tunnel are its simplicity to build and portability. The dataset contains design files for 3D printing of the wind tunnel, BOM and wiring of electronic components.

P版本）。该单元可实现精准测量：通过USB接口将数据实时上传至计算机进行连续记录，同时支持将数据存储至SD卡中。该风洞系统可提供最高4 m/s的气流速度参数，其流速测量的标准偏差为1.2%，湍流强度为1%。这款风洞的核心优势在于搭建简便且具备良好的便携性。本数据集包含该风洞的3D打印设计文件、物料清单（Bill of Materials，BOM）以及电子元件接线示意图。本项目仍处于原型开发阶段，作者不对因不当搭建或操作所导致的任何损坏或人身伤害承担责任。本资源的分发不提供任何明示或默示的担保，包括但不限于适销性、符合满意质量标准以及适用于特定用途的适用性。
