项目摘要
Smoke from bushfires transported by gravity currents, and known to occur nationwide, caused the shutdown of businesses, education and events in Canberra in 2019. Recent scientific investigations have shown that the speed of propagation and concentration of smoke in these three-dimensional gravity currents have a long term ‘memory’ of their initial configuration. In this project, high-fidelity computational and experimental techniques will be used to elucidate the fundamental mechanisms of gravity current entrainment and propagation. This knowledge will set a strong foundation to improve operational forecasts of smoke transport that will allow government agencies to better respond to the negative impact of these complicated flows.
2019 年,由重力流输送的丛林大火产生的烟雾导致堪培拉的商业、教育和活动停顿,该烟雾在全国范围内发生。最近的科学研究表明,这些三维重力流中烟雾的传播速度和浓度对其初始配置具有长期“记忆”。在该项目中,高保真计算和实验技术将用于阐明重力流夹带和传播的基本机制。这些知识将为改善烟雾输送的运营预测奠定坚实的基础,从而使政府机构能够更好地应对这些复杂流动的负面影响。
