Summary of the deposition fractions predicted by the CFD simulations of transnasal aerosol delivery to the preterm infant nasal model using the measured and flow-rate proportional aerosol emission profiles at a target peak flow rate of 3 L/min. The columns titled “Final (pushed)" contain data including suspended particles computationally deposited onto the nearest wall at the end of the simulation
