Abstract:
Flows in lung bifurcations are complicated by geometry, and it is recognized that accurate lung dosimetric models require realistic calculations of the flow and particle deposition patterns. A computational fluid dynamics study of flow and particle concentration has been carried out for a lung bifurcation based on the model developed by Weibel. The predicted flow patterns match well with previously reported experimental data. Secondary flow patterns and locations close to the walls having high particle concentrations are clearly seen.
