A numerical study of coagulation of nanoparticle aerosols injected continuously into a large, well stirred chamber

A new analytical solution for solving the population balance equation in the continuum-slip regime

“…(13) in Yu et al (2014). The program code of the SM used in this work has been verified in our previous works (Anand et al, 2012;Yu & Lin, 2009b), which is generally considered as a very accurate solution for solving the PBE . In the SM, the section spacing factor is 1.025 and the bin number is 360, which ensures the accuracy of the SM as a reference.…”

A bimodal moment method model for submicron fractal-like agglomerates undergoing Brownian coagulation

“…A similar dynamic process also occurs in particle synthesis engineering (Buesser & Pratsinis, 2012), workplace aerosol emission (Anand, Mayya, Yu, Seipenbusch, & Kasper, 2012), and dust storm and marine particles in the air (Jonasz, 2010;Whitby & McMurry, 1997). Brownian coagulation among different sized particles plays a key role in determining the evolution of size distribution in these particulate systems (Friedlander, 2000), whose dynamic process is theoretically governed by a population balance equation (PBE).…”

“…Therefore, the comparisons among these four studied B-TEMOM, B-QMOM3, B-QMOM4 and B-log MM models within each mode are taken into consideration in the present study. In a bimodal size distribution, the scavenging effect of Mode 1 on Mode 2 accounts for the main interaction mechanism between modes (Anand et al, 2012;Seipenbusch, Binder, & Kasper, 2008); thus, the differences in the geometric mean size, the magnitude and the geometric standard deviation between modes should be primarily considered. Similar works were performed in Jeong and Choi (2004) and Lee and Wu (2005).…”

Effective Coagulation Coefficient Approach for Estimating Particle Number Emission Rates for Strong Emission Sources

“…Eq. (8) is numerically solved using nodal method combined with finite difference scheme (Anand and Mayya, 2009;Anand et al, 2012) to obtain the steady-state number concentration with the following input parameters: S = 10 11 # m -3 sec -1 , CMD = 10 nm, GSD = 1.3, λ v = 0.5 h -1 . It is found that the estimate of the particle number emission rate (S) obtained from the K eff method is about 13% higher than S true value chosen for the numerical simulation.…”
