• Description:
  The dispersion of cough-generated bioaerosols was studied in an environmental chamber using a system that reproduces a typical human cough. Five aerosol optical particle counters were used to measure the number of particles and their size distribution over time after each cough. The chamber experiments were numerically simulated using the commercial CFD code, Ansys/Fluent. Particles were tracked using Lagrangian and Eulerian methodologies. Results from the models were compared to the experimental data to assess the performance of each method. The best-performing models were then used to create a numerical simulation of air and particle movement in the waiting room and examination rooms of the West Virginia University Urgent Care clinic. The flow field predicted by the simulations was used to estimate the best locations for bioaerosol sampling during a subsequent study of airborne influenza transmission.
