Ignitability, Quenching and Deflagration-to-Detonation-Transition of H2-air mixtures

这项工作旨在评估鲜为人知的氢气-空气混合物的可燃性，并对氢气-空气混合物的燃烧转爆轰机理有更深入的了解。氢气爆炸是当前英国核退役、废物和产品储存活动中的一个重大安全问题，例如在塞拉菲尔德。氢气-空气的着火和可燃性研究为评估滴滴涕的倾向性和发生时间提供了技术专长和知识，并开发了更知情的安全案例，以消除保守性，降低成本，缩短可能存在氢爆炸危险的核退役作业的时间。利兹大学宣布了一项新的研究战略，即“研究转型”，以实现低碳未来。拟议的核能工作与该大学的气候计划相一致，使1.5亿GB实现到2030年温室气体净零排放的目标。拟议中的氢气管理研究对赛拉菲尔德工厂的许多工厂来说是一个重大的常规安全隐患，并将在未来几十年的正常工厂运营中继续如此。利兹燃烧集团在热流体实验室G50中拥有一系列爆炸容器：世界知名的风扇搅拌爆炸容器，能够产生高度湍流；快速压缩机，能够精确测量自动点火延迟时间。这两个钻井平台有助于实现拟议的目标/目标。

The proposed work aims to evaluate ignitability of less known hydrogen-air mixtures, and obtain a greater understanding of Deflagration-to-Detonation mechanism of hydrogen-air mixtures. Hydrogen explosion is a significant safety concern during current nuclear decommissioning, waste and product storage activities in the UK, e.g. at Sellafield. Ignition and flammability research on hydrogen-air provides technical expertise and knowledge for assessing the proneness and onset of DDT, and developing better informed safety cases to remove conservatisms, reduce cost, timescales in nuclear decommissioning operations where hydrogen explosion hazards may exist. The University of Leeds has announced a new research strategy 'research transformed' to achieve a low carbon future. The proposed work on nuclear energy aligns with the University's Climate Plan, putting £150 million towards achieving the goal of net zero greenhouse gas emissions by 2030. The proposed research on the management of hydrogen is a significant conventional safety hazard at many plants on Sellafield site, and will continue to be so during normal plant operations for decades to come. Leeds Combustion group has a range of explosion vessels in Thermofluids lab G50: a world-renowned fan-stirred explosion vessel, capable of creating high levels of turbulence; a Rapid Compression Machine, capable of the accurate measurements of auto-ignition delay times. These two rigs help obtain the proposed aims/objectives.
