There has been a dimensionless treatment in Section 2.6 Dimensionless processing is used to compare the calculation accuracy between different mathematical models without considering the influence of the number and volume of particles. In this study, in the simulation process, the particle size span is large. The effective number of digits is limited, and the rounding error in the calculation process, so the calculation also uses dimensionless processing.
