Zusammenfassung
Das Strömungsverhalten in den Nasenhaupthöhlen wurde am originalgetreuen 1:1 Nasenmodell untersucht Alle Regionen beider Nasenhaupthöhlen konnten während einer Durchströmung untersucht werden. Die gezielte Anfärbung von Strombahnen zeigte, dass der Hauptatemstrom in Inspiration und Exspiration in den unteren Nasenabschnitten verläuft. In unseren Versuchen waren unter statischen Untersuchungsbedingungen laminare Strömungen aufgetreten, jedoch keine Bildung von Turbulenzen.
Summary
Airflow patterns of nasal cavities in a human nasal fossa model were examined in this study Our 1:1 model of the whole nose (both nasal fossae were moulded) gives a good insight into all parts of the nasal cavities. Staining of flow paths visualised that the main stream of air flow passes through the inferior nasal duct in inspiration and expiration. All regions of the nasal fossa were reached by fluid movements and could be marked with staining Solution. Under static conditions laminar flow without turbulent profiles was seen in all sections of the nasal cavities. This technique of detection of flow characteristics in the nasal cavities provides a good tool for further research on flow and deposition characteristics of aerosols.
