摘要:
为了评价通用CFD商业软件Fluent在液化天然气（LNG）泄漏扩散模拟上的适用性和有效性，借助于Coyote、Burro等液化天然气泄漏扩散试验数据，综合国外重气模型评价项目研究成果，设计了LNG泄漏扩散Fluent模拟有效性评价方法。先采用Fluent对LNG现场试验进行建模模拟；再将模拟结果与现场试验数据做偏差统计分析，最后将偏差统计值与判断标准及其他模型模拟的偏差统计值做比较，得出评价结果。评价结果表明：Fluent能有效地模拟预测LNG泄漏扩散危害浓度变化特征，且具有较好的预测精度，Fluent应用于LNG泄漏扩散风险评价有较高的可信性。
Abstract:
In order to evaluate feasibility and effectiveness of Fluent simulation for LNG release & dispersion,based on the datasets of LNG release field trials(Burro and Coyote) and the research results from the oversea Heavy Gas Dispersion Evaluation Protocols, an effectiveness assessing method of Fluent simulating LNG dispersion was presented. The assessing procedure was initiated by application of CFD software Fluent. The Statistical Performance Measures were then employed to evaluate the accuracy based on the assessment criteria as per statistics error between experimental data and those from predictions.It shows that Fluent could predict the characteristic of concentration variation from LNG release & dispersion effectively and accurately.It suggests that the results from Fluent simulation are reasonable and Fluent is a suitable CFD software for risk evaluation of LNG release & dispersion.
