HIGHLIGHTS
SUMMARY
Guo et_al identified SARS-CoV-2 in indoor air of hospital using SASS 2300 wetted wall cyclone sampler at a rather high sampling flow rate of 300 LPM (litre per minute), whereas (Chia et_al 2020) did it with a cyclone bioaerosol sampler at a much lower flow rate of 3.5 LPM. To these secondary flows along the walls, there is experimental evidence (as reported by Hoffmann and Stein ) that a "swiss roll" type of secondary flow pattern exists in the cyclone cone, which can cause particles to recirculate in the cyclone.
