ABSTRAKT
To analyse the dynamic flow in central airways, a workflow
has been established which finally enables numerical
simulation with simultaneous consideration of natural deformed
geometries and inversion of flow direction. Besides a
comprehensive description of the interdisciplinary methods,
variations of boundary conditions and parameters are discussed,
as well as method validations are presented. Finally,
selected insights to the flow field reveal important features
and emphasise the necessity of dynamic simulations.
