Abstract Nanoparticle distributions in a fully developed turbulent boundary layer are simulated numerically using the moment method. The effects of Schmidt number and Damköhler number on the nanoparticle distribution are studied. It is found that the particle number concentration and total particle mass increase from the wall to the outside. The difference of particle number concentration and total particle mass near the wall and near the outside becomes smaller with the increasing Schmidt number Sc. The particle diameter and geometric standard deviation increase from the wall to the outside at a fixed Damköhler number Da, and grow with the increase of Da at the same lateral position.
