title: [Computational fluid dynamics simulations of the airflow in the human nasal cavity].
abstract: OBJECTIVE
  This study represents an attempt to simulate the complex three-dimensional airflow pattern in the human nasal passageways.
  
  
  METHODS
  In the present study the computational Fluid Dynamics (CFD) have been used. The CFD solved numerically the flow governing equations. The CFD demonstrated to be a very efficient tool for researching on nasal flow.
  
  
  RESULTS
  By means of CT scan, an anatomic accurate three-dimensional representation of the human nasal cavity was obtained. Based on this model the influence of the inspiration and at the expiration at the flow pattern has been reviewed. The flow pattern is visualized by the velocity, pressure and turbulence intensity fields.
  
  
  CONCLUSIONS
  The flow patterns show the channel effect of turbinates and the influence of the breathing phase.
