Seminar 25 -- Movement and Control of Airborne Pathogens with HVAC Systems (LIVE)

This product is a zip file that contains files that consist of PowerPoint slides synchronized with the audio-recording of the speaker, PDF files of the slides, and audio only (mp3 format) as noted.

Airborne droplet and aerosols have been identified as contributors in transmission of various diseases like COVID-19. This seminar highlights case studies and CFD analysis of airflow patterns' impact on transmission of such airborne contaminants in buildings with higher air flow rates and ways to mitigate it. Also, it highlights the design and performance of a wind tunnel that helped in coronavirus aerosol collection for measurements and inactivation in lower air flow rates applications, such as in portable air purification systems. This seminar also describes pilot study of a novel PECO technology used to destroy airborne viruses in a hospital.
