Suspended particles can cause a wide range of chronic respiratory illnesses such as asthma and chronic obstructive pulmonary diseases, as well as worsening heart conditions and other conditions. To know the particle depositions in realistic models of the human respiratory system is fundamental to prevent these diseases. The main objective of this work is to study the lung deposition of inhaled particles through a numerical model using UDF (User Defined Function) to impose the boundary conditions in the truncated airways. For each generation, this UDF puts the values of velocity profile of the flow path to symmetrical truncated outlet. The flow rates tested were 10, 30 and 60 ℓ/min, with a range of particles between 0.1 µm and 20 µm.
