The deposition of monodisperse particles(1.0-26.0 mum diameter) in an idealized mouth-throat geometry has been studied numerically.The continuous phase flow is solved using a RANS(Reynolds averaged Navier-Stokes) turbulence model at inhalation flow rates of 90.0 and 30.0 1/min.The particulate phase is simulated using a random-walk/Lagrangian stochastic eddy-interaction model(EIM).Without near-wall corrections in the EIM,poor agreement is seen with experimental data on deposition.However,when a new near-wall correction in the EIM is implemented,the particle deposition results in the idealized mouth-throat geometry are in relatively good agreement when compared with measured data obtained in separate experiments.
