A new study used fluid dynamics simulations to study the effect of exercise at various ages on plaque formation in the arteries.

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...

COVID-19 transmission: Fast walking in narrow corridors can increase risk of viral spread  |  Photo Credit: iStock Images 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...

Narrow hallways pose higher infection risk; hospitalized COVID-19 patients often need readmission Reuters 16/12/2020 By Nancy Lapid (Reuters) - The following is a roundup of some of the latest scientific studies on the novel coronavirus and efforts to find treatments and vaccines for COVID-19, the illness caused by the virus. Narrow hallways present higher infection risks An unmasked coronavirus-infected person walking fast down a narrow corridor leaves a long stream of virus-laden droplets trailing behind, a new computer simulation suggests. Even if social distancing guidelines are follo...
