Abstract
Ammonia is a high-efficiency and safe hydrogen storage medium. Pipeline transport offers significant economic benefits for long-distance ammonia transportation. However, due to ammonia's toxicity, accidental leaks during transportation can lead to catastrophic consequences. Therefore, a comprehensive understanding of the dispersion characteristics of liquid ammonia pipeline leaks is essential for safety measures. Prior studies focused on the ammonia dispersion over flat terrain, leaving a gap in understanding the impact of diverse terrains on dispersion dynamics. This study introduces a computational fluid dynamics model to simulate ammonia dispersion over complex terrain, quantifying the influence of topographical features on dispersion consequence distances. Firstly, validation of the numerical model is conducted using a custom-built open-circuit wind tunnel test platform. Secondly, the dispersion of ammonia is analyzed over six representative terrains, highlighting the influence of complex topographies on the consequence distances. Additionally, the effects of leakage flow rate, atmospheric stability, and leakage direction on dispersion over flat terrain are examined. Finally, a comprehensive assessment of potential risks associated with liquid ammonia pipeline leaks across various terrains is provided by the synthesis and analysis. The results indicate that flat terrain simulations cannot conservatively estimate consequence distances for most terrains. Therefore, incorporating local terrain data in dispersion simulations is recommended to determine the impact area accurately.
期刊介绍：
The Process Safety and Environmental Protection (PSEP) journal is a leading international publication that focuses on the publication of high-quality, original research papers in the field of engineering, specifically those related to the safety of industrial processes and environmental protection. The journal encourages submissions that present new developments in safety and environmental aspects, particularly those that show how research findings can be applied in process engineering design and practice.
PSEP is particularly interested in research that brings fresh perspectives to established engineering principles, identifies unsolved problems, or suggests directions for future research. The journal also values contributions that push the boundaries of traditional engineering and welcomes multidisciplinary papers.
PSEP's articles are abstracted and indexed by a range of databases and services, which helps to ensure that the journal's research is accessible and recognized in the academic and professional communities. These databases include ANTE, Chemical Abstracts, Chemical Hazards in Industry, Current Contents, Elsevier Engineering Information database, Pascal Francis, Web of Science, Scopus, Engineering Information Database EnCompass LIT (Elsevier), and INSPEC. This wide coverage facilitates the dissemination of the journal's content to a global audience interested in process safety and environmental engineering.
