V D&#x;Alessandro et al.
It is well known that several viruses, as well as SARS-CoV-2, can be transmitted through airborne diffusion of saliva micro-droplets. For this reason, many research groups have devoted their efforts in order to gain new insight into the tra...
Large eddy simulation of cough jet dynamics, droplet transport, and inhalability over a ten minute exposure [0.03%]

A dominant mode of transmission for the respiratory disease COVID-19 is via airborne virus-carrying aerosols. As national lockdowns are lifted and people begin to travel once again, an assessment of the risk associated with different forms ...
Numerical modeling of the distribution of virus carrying saliva droplets during sneeze and cough [0.03%]
喷嚏和咳嗽时携带病毒的唾液飞沫分布的数值模拟
