Abstract

CFD analysis is an alternative to the using an experimental model for modeling nasal airflow. In this study, a mesh was created from an MRI, and imported into Fluent for analysis. Simulations were run with various models, which were then compared with each other. Models were also run with both laminar and k-epsilon turbulence models. For this patient and these particular flow patterns and geometry, the flow was determined to be quasi-steady since the steady and unsteady models correlated well with each other. Also, it was found that the choice of which viscous model to use (in this case, k-epsilon vs. laminar) was found not to play a significant role in the outputs. Finally, the results of this study were somewhat different from the results determined experimentally.
