Scientists in Finland have created a model of how tiny airborne virus particles spread indoors, like the structure of a grocery store. They claim that the model they created will help us better understand how the new coronavirus spreads. This information was given in a report of Live Science.
A joint research team from Alto University in Finland, the Finnish Meteorological Institute, the Vtitis Technical Research Center and the University of Helsinki have worked on the study. They have used supercomputers to model how small viral particles spread through a person's respiratory tract through sneezing or coughing.
In their research work, they have created an artificial scene where if a person sneezes or coughs between two shelves of the shop, the air circulation can be taken into account.
Will Vurinen, an assistant professor in the Department of Mechanical Engineering at Alto University who studies fluid dynamics, said in a statement that while researching coronavirus diffusion models, they found that when a person coughs, aerosols form "clouds" around them and slowly disperse and merge. However, this process takes a few minutes to complete. During this time, if one walks through the condensed cloud-like area, the theory is that these virus particles enter with their breath.
Vurinen said anyone infected with the coronavirus could go away coughing, but he left behind extremely small aerosol particles that carry the coronavirus. These particles can be inhaled by others in the vicinity.
Based on the research, researchers in Finland are now advising people to avoid areas that are more crowded and areas that are more crowded.
Researchers have modeled the movement of aerosol particles smaller than 20 micrometers, so that there are even tiny particles that can float in the air and move with air rather than falling on a surface.
The researchers say they will work to further improve the model they have created and also improve the visualization process to better understand the movement of airborne particles.
