Improvement on particle deposition prediction in the intermediate size range based on the moment method
The accurate prediction of particle deposition in confined space is of vital importance in the environmental and industrial fields.This study focuses on correcting slip correction factor to elevate the accuracy of these models.Primarily,the slip correction factor,a pivotal parameter in closed chamber particle deposition,undergoes correction to bring the deposition coefficient into closer alignment with exact values,augmenting the reliability of predictive models.Furthermore,based on the log-normal size distribution theory,the moment method(MOM)is used to model the deposition model of aerosol particles,and the distribution results of particles in the transition zone size range are predicted.By comparing the corrected solutions with traditional moment method solutions as well as exact solutions,the new solutions of the moment method show higher accuracy in particle number concentration,mean geometric standard deviation,and particle distribution.The relative error of the new solution for particle number concentration is reduced by 43.43％,compared with the traditional moment method solution in the intermediate size range.At last,this research verified the corrected solutions with the experimental data from the literature.
