Zusammenfassung
Zur Untersuchung der laminaren inkompressiblen Grenzschicht an dünnen Profilen wird eine einfache Expansionsmethode angegeben. Diese Methode verbindet die Entwicklung für kleine Störungen mit den «quasi-ähnlichen» Theorien der Grenzschicht. Verschiedene geometrische Formen wurden behandelt, einschliesslich eines Joukowski-Profils, eines Parabel-Profils und eines schlanken Keils. Die erhaltenen Profile und Reibungswerte sind in guter Übereinstimmung mit Resultaten aus anderen Quellen, selbst für ziemlich dicke Profile. Die Anwendung der Methode dürfte besonders nützlich werden im drei-dimensionalen Fall, wo andere zwei-dimensionale Methoden nicht einfach übertragen werden können.
