It is known that microorganism transport is enhanced during the normal coughing process, which can be responsible for the spreading of communicable diseases. The prediction of particle characteristics generated during a normal cough within confined spaces will help to better understand human exposure health concerns. Results of a computational fluid dynamics study, CFD, of the particle and flow field behavior within a square environmental chamber, performed using the Discrete Phase Model available in the commercial CFD numerical package FLUENT are presented.
