本文旨在开发和验证一个计算流体动力学（CFD）模型，用于模拟加氢站（HRS）整个设备的加氢过程。这种模型的缺乏阻碍了HRS设备、氢存储参数和环境条件的任意组合的本质上更安全的加油协议的设计。在国家可再生能源实验室（NREL）进行的1号试验中，对持续195 s的换料完整过程进行了CFD模型验证。测试设备包括HRS的高压罐、压力控制阀（PCV）、阀门、管道、分离器、软管和喷嘴，最多可达三个车载罐。该模型准确地再现了HRS设备整个生产线的氢气温度和压力。CFD模型与简化模型的一个突出特点是能够预测机载油箱中的温度不均匀性，这是一个具有重大安全意义的关键因素。
This paper aims at the development and validation of a computational fluid dynamic (CFD) model for simulations of the refuelling process through the entire equipment of the hydrogen refuelling station (HRS). The absence of such models hinders the design of inherently safer refuelling protocols for an arbitrary combination of HRS equipment, hydrogen storage parameters, and environmental conditions. The CFD model is validated against the complete process of refuelling lasting 195s in Test No.1 performed by the National Renewable Energy Laboratory (NREL). The test equipment includes high-pressure tanks of HRS, pressure control valve (PCV), valves, pipes, breakaway, hose, and nozzle all the way up to three onboard tanks. The model accurately reproduced hydrogen temperature and pressure through the entire line of HRS equipment. A standout feature of the CFD model, distinguishing it from simplified models, is the capability to predict temperature non-uniformity in onboard tanks, a crucial factor with significant safety implications.
