Plaque formation in the arteries carrying blood to the head and neck is a serious medical problem, potentially leading to strokes and heart attacks. In Physics of Fluids, by AIP Publishing, engineers from China use fluid dynamics simulations to study the effect of exercise at various ages on plaque formation.

For the research, which was published in the journal
Physics of Fluids, the team tapped into computer simulations to predict how coronavirus-laden droplets disperse through the air.
Past investigations utilizing a similar simulation technique have assisted scientists to better understand the influence of various objects, such as glass barriers, windows, air conditioners, and toilets, on airflow patterns and spread of viruses.
In most cases, those simulations only used large, open indoor spaces and didn’t consider the effects of nearby walls, which would be present in a narrow corridor.
The results revealed that when an individual coughs while walking quickly down a corridor, the expelled droplets were found to travel around and behind the body and potentially infecting people trailing behind. In many instances, children had a higher transmission risk.

Beijing: Fast walking in narrow spaces behind a group of people can significantly increase COVID-19 transmission risk, especially in children, according to a study which says virus-laden respiratory droplets can trail behind infected individuals moving through such corridors.
The results of the computer simulation, published in the journal Physics of Fluids, underscored the importance of the shape of spaces in predicting how virus-laden droplets move through the air.
