Speziell rotierende Systeme wie die K\u00fchlventilatoren des Elektromotors oder der Turbolader der Brennstoffzelle sind dabei Hilfsaggregate, denen eine gro\u00dfe Bedeutung zukommt. Messungen an gro\u00dfen Versuchsaufbauten, um die Mechanismen, die in diesen Systemen L\u00e4rm verursachen zu verstehen, sind dabei h\u00e4ufig zu kosten- und zeitintensiv. Demzufolge werden immer h\u00e4ufiger komplexe Simulationen verwendet, um tiefergehendes Wissen \u00fcber die Str\u00f6mungsakustik in rotierenden Systemen aufzubauen.
