流动物理学在COVID-19大流行的几乎每个方面都发挥着关键作用。这包括从宿主产生和雾化携带病毒的呼吸道飞沫，其空气传播和沉积在表面上，以及随后被不知情的接受者吸入这些生物气溶胶。流体动力学也是预防措施的关键，例如使用口罩，洗手，室内环境通风甚至社交距离。本文总结了我们所知道的，更重要的是，我们需要了解这些问题背后的科学，以便我们更好地准备应对下一次COVID-19或类似疾病的爆发。
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.
