Abstract

Die Erfindung betrifft eine Strömungsmaschine, die aufweist: mindestens einen Rotor (11, 21, 31), der einen Drehkörper mit einer Mehrzahl von an dem Drehkörper angeordneter Laufschaufeln (12, 22, 32) aufweist, und ein Umfangsgehäuse (15, 25) mit einer Mittelachse (2), das den Rotor (11, 21, 31) umgibt, wobei das Umfangsgehäuse (15, 25) oder ein mit diesem verbundenes Teil (9, 9') innenseitig eine Ringraumfläche (16, 26, 26a, 26b) aufweist, die einen Strömungskanal (3, 4) der Strömungsmaschine radial außen begrenzt, und die Ringraumfläche (16, 26, 26a, 26b) zumindest in einem Bereich, der umfangsseitig an einen Rotor (11, 21, 31) angrenzt, eine Strukturierung aufweist. Es ist vorgesehen, dass mindestens eine Strukturierung (6, 7) der Ringraumfläche (16, 26, 26a, 26b) bezogen auf die Mittelachse (2) des Umfangsgehäuses (15, 25) umfangsasymmetrisch ausgebildet ist.
