Maria Fölling-Albers,Werner Föllingzzle concepts and different afterbody geometries. The flow phenomena are characterized by experimental measurements and numerical URANS and LES simulations. Investigations concern a configuration with a conventional truncated ideal contour nozzle and a configuration with an unconventional dual-bell

vels. The afterbody geometry is varied including a reattaching and non-reattaching outer flow on the nozzle fairing. Investigations are performed at supersonic outer flow conditions with a Mach number of .. It turns out, that a reattachment of the outer flow on the nozzle fairing leads to an unstabl

Maria Fölling-Albers,Werner Föllingtric and longitudinal wave-like structures on the dense oxygen core. With the gained understanding of the BKD coupling mechanism it was possible to derive LOX injector geometry changes in order to reduce the risks of injection-coupled instabilities for future cryogenic rocket engines.

Für die Mehrheit der Kibbutzim läßt sich jedoch sagen, daß die Bund-Phase in der Regel die Gründungsphase in den 20er und 30er Jahren gewesen ist, daß sie in den 50er Jahren Merkmale der Kommune hatten und ab den 60er Ja
