An inertial theoretical model is proposed to predict the capture of aerosol particles by accelerating liquid droplets in a centrifugal fan scrubber. The results are in good agreement with literature experimental data for micron and large submicron size particles. The theory tends to underestimate the scrubber performance for submicron size particles of less than 0.3 μm in diameter. The discrepancy may be due to the lack of a reliable expression predicting the diffusion deposition of aerosol particles on an isolated liquid droplet. The effects of variables such as fan speed, sizes of liquid droplets and particles, gas and liquid flow rates predicted by the theory are discussed and agree with literature observation.
