People around you are coughing and sneezing, and you find yourself holding your breath or averting your face an awful lot lately. Whenever flu season is setting in, everyone is quick to blame another person for catching a cold. But have you ever realized that the building or environment might be the actual ‘bad guy’ here? A Japanese university conducted research on this subject using MSC Software’s Cradle-CFD – and had some very interesting findings to share.

Packed in a classroom: prone to the flu?

Researchers decided to perform a case study, simulating the spread of a virus in a classroom environment and assigning certain characteristics – such as coughing – to it. The goal: see how the virus would develop in the classroom.

Assuming a cold winter’s day, the flu viruses were modeled and calculated as diffusion species transported by the air flow. The latter was calculated using a steady-state simulation with buoyancy. Then, the diffusion of the virus was determined through transient simulation. The conclusion? The virus, which is spread by air, is actually ‘guided’ to ‘hit’ as few students as possible.

Cradle-CFD: thermo-fluid analysis software for increased understanding

This research has been performed using Cradle-CFD, an MSC Software product that can simulate and predict the flow of liquids. The types of research made possible by it serve to increase an engineer’s understanding while providing a vehicle for communicating this newly gained knowledge to non-experts – as the above case study excellently shows.
