Abstract

<p>By calculating trajectories of aerosol particles by Langevin dynamics method, in which random motion of aerosol particles are represented by pseudo random number, coagulation coefficient of aerosol was calculated. Both interval times between collision of one particle with other particles, and concentration distribution of particles were calculated in MTBC method: it was utilized to investigate the coagulation coefficient in transition regime. Coagulation coefficient obtained by the MTBC method corrected by concentration of particle at infinity are smaller than that obtained by flux matching method by Fuchs (1964). This suggests that the assumption made in the flux matching method does not hold completely. Then, in order to develop numerical model of change in particle size distribution by coagulation, GPGPU was employed to calculate the coagulation coefficient by parallel computing of motion of large number of particles.</p>
