Numerical simulations of coagulating and dispersing nanoparticles in an incompressible turbulent planar jet with constraints are performed. The evolution of nanoparticle field is obtained by utilizing a moment method to approximate the particle's general dynamic equation. The spatiotemporal evolution of the first three moments along with the mean particle diameter and geometric standard deviation of particle diameter are discussed
