Abstract

Beschrieben wird eine Vorrichtung sowie ein Verfahren zur Prallkühlung eines in einer Strömungsmaschine hitzeexponierten Bauteils mit einem zu kühlenden Wandabschnitt, der wenigstens einseitig wenigstens einem Prallluftkühlstrom ausgesetzt ist, der durch einen Strömungskanal innerhalb eines Flächenelementes, das beabstandet gegenüber dem zu kühlenden Wandabschnitt angeordnet ist, hindurchtritt und auf den zu kühlenden Wandabschnitt auftrifft.
Die Erfindung zeichnet sich dadurch aus, dass der Strömungskanal eine Eintritts- und eine Austrittsöffnung aufweist, dass die Austrittsöffnung unmittelbar dem zu kühlenden Wandabschnitt zugewandt ist, und dass die Eintrittsöffnung einen Durchströmungsquesrschnitt aufweist, der kleiner als der Durchströmungsquerschnitt der Austrittsöffnung ist.
