Preliminary prediction of flow and particulate concentration produced from normal human cough dispersion

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.
