摘要:
为揭示油气扩散规律,建立风洞平台,并以敞口式油罐为例,结合数值模拟技术,讨论储罐内油气扩散风洞实验准则数的适用性问题。发现不同液位下满足原型与模型的相似与雷诺数(Re)无关的临界雷诺数(Recrit)均为22 436。在满足Re无关的基础上,分别根据密度弗劳德数(Frρ)相等原则和Nemoto准则得到最大限度满足原型与模型相似的原型和模型(即风洞实验)风速及相关参数,构建原型模拟和风洞实验。利用风洞实验得到的油气浓度分布验证原型模拟结果,发现基于Frρ相等原则设计的风洞实验和原型模拟的浓度分布具有较高的一致性,而基于Nemoto准则设计的风洞实验和原型模拟的浓度分布相差较大。因此,不建议使用Nemoto准则设计储罐的油气扩散风洞实验。研究成果可为研究油气扩散规律的风洞实验设计做参考。
Abstract:
A wind tunnel platform was built to reveal the law of oil vapor diffusion. Based on numerical simulation technology, the applicability of the similarity criterion number of the wind tunnel was discussed by taking an open oil tank as an example. The results show that the velocity distribution would be always independent of the Reynolds number(Re)when Re≥22,436 for three different liquid levels. Furthermore, under the condition of Reynolds-independent, the wind speeds and the relevant parameters of the wind-tunnel experiments(i.e. model experiments)and numerical simulations for the prototype were obtained by using the density Froude number(Frρ)equivalence which means Frρ of the model is equal to that of the prototype and Nemoto criterion, respectively. Then prototype simulations and wind tunnel experiments were constructed based on the wind speeds and the relevant parameters. The results show that there is a high consistency between the distributions of oil vapor concentration obtained from the prototype simulation and wind tunnel experiments based on Frρ equivalence, which shows that the prototype simulation results are reliable. However, there is a great difference between the distributions of oil vapor concentration obtained from the prototype simulation and wind tunnel experiments based on Nemoto criterion. The research results can be used as a reference for the wind tunnel experimental design to investigate the law of oil vapor diffusion.
