TY - JOUR TI - High concentration Brownian coagulation in jet flow using two enhancement formulations AU - Lin Pei-Feng AU - Wu Di-Chong AU - Zhu Ze-Fei JN - Thermal Science PY - 2012 VL - 16 IS - 5 SP - 1519 EP - 1523 PT - Article AB - Ultra-fine particle coagulation by Brownian motion at high concentration in planar jet flow is simulated. A Taylor-Series Expansion Method of Moments is employed to solve the particle general dynamic equation. The volume fraction gets high value, very closes to that at the nozzle exit. As the vortex pairing develops, the high volume fraction region rolls out and mixes with the low value region. The enhancement factor given by Trzeciak et al. will be less than one at some specific outer positions, which seems to be less accurate than the one given by Heine et al.
