Abstract

Bei der Prallluftkühlung von Gasturbinenkomponenten werden Prallluftöffnungen mit Kühlluftgeschwindigkeitspaketen von bestimmter Amplitude in einer vorgegebenen Frequenz beaufschlagt, wobei sich aufeinander folgende Ringwirbelstrukturen ausbilden, die die Querströmung durchdringen und mit hoher Intensität auf das zu kühlende Bauteil treffen und dadurch für eine effiziente Kühlung sorgen. Zur Erzielung von Ringwirbelstrukturen mit optimaler Kühlwirkung liege die Strouhalzahl, die durch das Verhältnis zwischen der Amplitude und der Frequenz der Geschwindigkeitspakete und der Größe der Prallluftkühlöffnungen bestimmt ist, zwischen 0,2 und 2,0, vorzugsweise zwischen. 0,8 und 1,2.

Figure imgaf001
In the impingement air cooling of gas turbine components, impingement air openings are exposed to cooling airspeed packets of a specific amplitude at a predetermined frequency, forming successive annular vortex structures that penetrate the crossflow and strike the component to be cooled with high intensity and thereby ensure efficient cooling. To obtain ring vortex structures with optimum cooling effect, the Strouhalzahl, which is determined by the ratio between the amplitude and the frequency of the speed packets and the size of the Vorallluftkühlöffnungen, between 0.2 and 2.0, preferably between. 0.8 and 1.2.
