Noninvasive aerosol removal processes are sought for in powder product recovery. Acoustically induced aerosols depositions were proposed as an alternative to the traditional cyclone separator technique. We examined the ability for aerosol removal on different aerosol input, categorized by the particle initial concentrations and size distributions. Both experimental and simulated studies were performed and a non-dimensional parameter, deposition cell ratio was established as the underlying parameter which governed deposition for different size aerosols.
