Correcting the multi-Monte Carlo method for particle coagulation

Multi-Monte Carlo (MMC) method does not correctly treat the results of coagulation event between two differentially-weighted simulation particles, resulting in comparatively large error in predicting the evolution of particle size distribution. This study corrected the consequential treatment of coagulation event, satisfying the basic laws of mass conservation and number depletion and then resulting in good prediction for particle size distribution. The corrected MMC method can complete with any available Monte Carlo methods with respect to computational accuracy.

Graphical abstractThe conceptual difficulty of imagining a coagulation event between two differentially-weighted simulation particles in Monte Carlo method for population balance is solved, which greatly updates the numerical precision of the original multi-Monte Carlo method for the dynamic evolution of particle size distribution. The corrected MMC method can complete with any available Monte Carlo methods with respect to computational accuracy.Figure optionsDownload full-size imageDownload as PowerPoint slide
