Reference experiment on aerosol particle transport for dynamic situations

To study aerodynamic transport of aerosol particles within closed room dynamic situations, the Cottbus Aerosol particle Reference Experiment (CARE) was built and equipped, which includes thermal manikins and a spreader dummy. For various flow configurations (location of spreader, heating bodies, windows opened, air ventilation with and without air purification systems) flow visualisation is performed, particulate matter sensors (PMS) measure local particle concentrations, head mounted camera systems count particle concentrations of individuals and finally, large field of view Shake-The-Box Particle Tracking
delivers velocity fields. The comprehensive experimental configuration of different measurement systems are discussed in terms of their quantitative results, effective application and comparative efficiency explaining the flow dynamics. The findings from these experiments also provide information under which circumstances particularly high concentrations of aerosol particles can be found on which locations.
