摘要：
This paper introduces an aerosol atomization factor to calculate the mass emission rate of oil particles using the maximum fluid flow rate for atomization obtained from a theoretical model. The particle size distribution is obtained by the Rosin-Rammler function. An environmental chamber is used to obtain the mass median diameter and the distribution coefficient of the Rosin-Rammler function, as well as the aerosol atomization factor. The particle emission rate is then modelled for each particle size.The experimental data show that the mass emission rate of oil particles ranges from 14.58 to 620.95 mg•h-1. Both the particle emission rate and the aerosol atomization factor increase with tool rotational velocity. Moreover, the aerosol atomization factor is a linear function of the tool rotational velocity, with a determination coefficient R² of 0.998. The model established in this paper represents the oil particle emission rate accurately for each particle size, with an average error of 3.69±12.7 mg•h-1. © 2020, Editorial Department of Journal of Tongji University.
