Towards a predictive capability for the resuspension of particles through extension and experimental validation of the Biasi implementation of the “Rock'n’Roll” model

Influence of the transient airflow pattern on the temporal evolution of microparticle resuspension: Application to ventilated duct during fan acceleration

“…Figure 6 also confirms, as mentioned by Braaten, Paw, and Shaw (1990), Kassab et al (2013), andVincent et al (2019), that the temporal evolution of the remaining fraction is sharper during acceleration than at steady state. The remaining fraction keeps decreasing as steady state is reached but significantly more slowly.…”

“…Except Kassab et al (2013) who reported fractions of detached particles obtained at high acquisition frequency (of 2000 Hz), there are no other studies in the literature that addressed the dynamic of resuspension through such time-resolved approach. Braaten, Paw, and Shaw (1990), Ibrahim, Dunn, and Brach (2003), and Vincent et al (2019 presented detached fractions versus time for temporal airflow patterns involving an acceleration period followed by steady state, but the acquisition frequencies were too low to have a fine description of the evolution of the phenomenon during the acceleration stage which is generally rather short.…”

Aerosol Populations, Processes, and Ages in Bulk Deposition: Insights From a 9‐Year Study of 7Be, 210Pb, Sulfate, and Major/Trace Elements

“…The resuspension and recycling of aerosols is widely recognized in biogeochemical cycles of pollutants, MTEs, and FRNs alike. Radioactive aerosols generated in nuclear bomb testing and industrial accidents show that aerosols remain in recirculation at the earth surface for years following deposition at a rates of 1%–10% of total deposition (e.g., Anspaugh et al., 2002; Kinase et al., 2018; Vincent et al., 2019). Isotopic measurements of stable Pb and 210 Pb reveal that legacy anthropogenic Pb from gasoline combustion persists in the surface environment decades after its banning (Farmer et al., 2010; Yang & Appleby, 2016).…”

Patterns and Processes in Aerosol Bulk Deposition: Insights from a 9-year Study of 7Be, 210Pb, Sulfate and Major/Trace Elements

“…The resuspension and recycling of aerosols is widely recognized in biogeochemical cycles of pollutants, MTEs and FRNs alike, but quantifying and characterizing this fraction remains a challenge. The highly-traceable radioactive aerosols generated in nuclear bomb testing and industrial accidents show that aerosols remain in recirculation at the earth surface for years following deposition (e.g., Kinase et al 2018) at a rates of 1-10% of total deposited amount (Anspaugh et al 2002, Vincent et al 2019. Isotopic measurements of stable Pb and 210 Pb reveal that legacy anthropogenic Pb from gasoline combustion persists in the surface environment several decades after its banning Appleby 2016, Farmer et al 2007 ).…”
