With no vaccine expected for Covid-19 anytime soon, preventing its spread could be as important as treating it. In this special edition of ASME TechCast, Managing Editor Chitra Sethi speaks with Professor Qingyan Chen, the James G. Dwyer Professor of Mechanical Engineering at Purdue University, who has researched the spread of viruses through ventilation systems in passenger vehicles. He believes cruise ship air conditioning systems are not designed to filter out particles as small as the coronavirus, allowing the disease to rapidly circulate to other cabins. Prof. Chen’s lab is currently developing a ventilation system that would prevent the airborne transmission of pathogens like Coronavirus by allowing each person to breathe in only his or her own air.
