In this research, study on the advection of particle size distribution was carried out using the 2D axisymmetric CFD model available in COMSOL Multiphysics v5.6. The aim of this research is gain insight into the movement of particles using a simplified 2D axisymmetric CFD model. The simplicity of the model allows for the relatively rapid generation of results as compared to the result generation time of high-fidelity 3D models and easy customization as opposed to experimental setups. The results presented here are focused on the change in the size distribution of particles that reach a target location and the fraction of the total particle volume initially emitted by the transmitter that reach a target location. Analysis of the results from different perspectives provide insight into the advective behaviour of the particles and the evolution of size distribution as the particles are delivered to target locations. To obtain the results, field flow simulations are carried out first, followed by particle tracking simulations.
