On the effective density of non-spherical particles as derived from combined measurements of aerodynamic and mobility equivalent size
O Schmid, E Karg, DE Hagen, PD Whitefield… - Journal of Aerosol …, 2007 - Elsevier
Effective densities derived from combined mobility and aerodynamic sizing provide a
valuable tool for the characterization of non-spherical particles. Different effective densities
have been introduced depending on the primary measurement parameters (mass, mobility
and/or aerodynamic size) and the flow regime (transition, free-molecular). Here we explore
the relationship between these effective densities, their physical interpretation and their
dependence on particle shape, density and various equivalent diameters. We also provide …
