论文摘要
流体物理学在Covid-19大流行的几乎每个方面都起着关键作用。这包括从宿主那里产生和气化病毒呼吸道液滴，其空气传播的分散和沉积在表面上，以及随后通过毫无戒心的接受者对这些生物溶质的吸入。流体动力学也是预防措施的关键，例如使用面罩，洗手，室内环境的通风甚至社交距离。本文总结了我们所知道的，更重要的是，我们需要了解有关这些问题的科学所需的知识，以便我们可以更好地准备解决Covid-19或类似疾病的下一次爆发。
Flow physics plays a key role in nearly every facet of the COVID-19 pandemic. This includes the generation and aerosolization of virus-laden respiratory droplets from a host, its airborne dispersion and deposition on surfaces, as well as the subsequent inhalation of these bioaerosols by unsuspecting recipients. Fluid dynamics is also key to preventative measures such as the use of face masks, hand-washing, ventilation of indoor environments, and even social distancing. This article summarizes what we know, and more importantly, what we need to learn about the science underlying these issues so that we are better prepared to tackle the next outbreak of COVID-19 or a similar disease.
