摘要:
氢能是有发展前景的新型能源之一,氢气的安全储存是氢能应用必须解决的问题。本文建立了基于大容量金属储氢装置的室内氢气泄漏扩散模型,利用计算流体力学软件FLUENT,对室内储氢罐的泄漏扩散过程进行数值模拟,得到了氢气泄漏扩散的速度分布、浓度分布。分析数值模拟结果,得出在该模拟条件下,氢气泄漏时的流动状态为射流湍流;泄漏后上浮扩散,空间密闭时积累于室顶;通风条件下大部分区域的氢气浓度仍然高于安全限值。通过数值模拟,总结出氢气在室内环境下的泄漏扩散规律,可为氢气泄漏事故的处理消防安全设置提供依据。
Abstract:
Hydrogen energy is one of new types of energy with tremendous potentials,the safety of hydrogen storage is a problem which must be solved in the process of hydrogen energy’s application.This paper built a leakage and diffusion model of high capacity metal hydride hydrogen storage tanks in indoor environment.By numerical simulations about leaking and difffusing process of hydrogen storage tanks based on computed fluid dynamic software FLUENT,hydrogen’s velocity and mass fraction distributings were obtained.The results of numerical simulation to get conclusions that hydrogen’s flowing status was injecting and turbulent when leaking;which floated upward and diffused,accumulated on top layer of room in airtight situation.The concentration exceeded safety limit in most of the space in ventilative situation.Hydrogen’s leakage and diffusion rules of indoor environment were summarized by numerical simulation,which can provide reference for dealing with the hydrogen leakage accident and fire protection establishments.
