Abstract

Ein Kanal, in welchem ein Fluid leitbar ist, ist von Kanalwänden begrenzt, wobei die Kanalwände eine Eintrittsöffnung und eine Austrittsöffnung aufweisen, durch welche das Fluid in den Kanal eintreten kann und den Kanal verlassen kann. Das Fluid weist eine Strömungsgeschwindigkeit (15) auf, welche entlang der Kanalwände kleiner als in der Kanalmitte ist, sodass im Kanal eine Zone höherer Strömungsgeschwindigkeit und eine Zone niedrigerer Strömungsgeschwindigkeit ausbildbar ist. Im Kanal ist eine Strömungsleitfläche (24) angeordnet, mittels welcher ein Teil des Fluids aus der Zone höherer Strömungsgeschwindigkeit abschöpfbar und in die Zone niedrigerer Strömungsgeschwindigkeit einmischbar ist.
