Production of rounded Ti- and Al-hydroxide particles in a turbulent jet by coagulation-controlled growth followed by rapid coalescence

Investigation on the coagulation and deposition of combustion particles in an enclosed chamber with and without stirring

“…Based on our experiments and the range of values in the references in Table 4 we also contribute the charging effect as one of the major factors leading to the scattered results. Stirring does not result in a significant change of the coagulation coefficient in this study, which is in agreement with the findings of Lesniewski and Koch (1998). They investigated the turbulence of a jet flow and stated that depending on the Kolmogoroff scale Kol of the flow and the stopping distance s of particles it can be estimated whether Brownian coagulation or turbulent coagulation prevails.…”

Chemical Characterization of Flowing Polydisperse Aerosols by Raman Spectroscopy

“…The smaller ow stream was then diluted by approximately 100:1, and the larger stream was discarded. The resulting diluted aerosol stream was routed to a vessel from which samples were extracted using a venturi dilution probe (Lesniewski and Koch 1998). The sampling probe gave dilution factors between 100:1 and 300:1 and was sensitive to operating conditions.…”

A reference aerosol generator based on Brownian coagulation in a continuously fed well stirred tank reactor

“…p,n derived by Lesniewski and Koch (1998) holds. Here, C V 0 , is the volume fraction of the condensed aerosol precursor corresponding to its saturation concentration in the nozzle at the saturation temperature T S .…”
