In this paper, we extend the method so as to consider the electrostatic eãect in the calculation of the dynamics of dust. In the method of Honda et al., a dust is moved in a Lagrangian manner according to the çow velocity at the position of the dust. In the extended method of this paper, the dynamics of a dust is analysed by solving numerically the equation of motion of a dust. The motion of a dust is aãected by three kinds of external forces, namely, the electrostatic force, the drag due to air çow in a room and the gravitational force. Numerical calculations by the extended method have yielded the realistic tendency of dust motions. Encouraging results are obtained. 中央大学理工学研究所 2019-03-31 jpn departmental bulletin paper VoR https://doi.org/10.24789/00012107 https://chuo-u.repo.nii.ac.jp/records/12122 10.24789/00012107 1343-0068 中央大学理工学研究所論文集 24 13 27 https://chuo-u.repo.nii.ac.jp/record/12122/files/1343-0068_24_13-27.pdf application/pdf 1.2 MB 2020-06-21
