TY - JOUR TI - Brownian coagulation of aerosols in transition regime AU - Chen Zhong-Li JN - Thermal Science PY - 2012 VL - 16 IS - 5 SP - 1362 EP - 1366 PT - Article AB - The collision efficiency of Brownian coagulation for monodisperse aerosol particles in the transition regime is considered. A new expression for collision efficiency is proposed taking into account the influence of tangential relative motion when two particles get close enough during the diffusion process. The breakaway point from which the theory of near continuum regime no longer applies can thus be obtained easily. A comparison with experimental measurements shows the accuracy of the results predicted by the new theory.
