opposite the first end, the middle portion comprising: an interaction chamber, a fluid supply inlet for introducing a fluid stream into the interaction chamber, an outlet nozzle disposed at the second end of the middle portion and downstream of the fluid supply inlet, wherein a fluid stream exits the interaction chamber through the outlet nozzle, the outlet nozzle having a first end, a second end, and a narrowest portion disposed between the first end of the outlet nozzle and the second end of the outlet nozzle, wherein the narrowest portion of the outlet nozzle has a smallest inner area in a plane parallel to the second end of the middle portion, and the first end of the outlet nozzle being closer than the second end of the outlet nozzle to the fluid supply inlet, and a first control port and a second control port, the first control port and the second control port each having a flow direction (161, 163), the first control port and the second control port for introducing a control fluid into the fluidic oscillator in the flow direction (161, 163) or suctioning the fluid stream from the fluidic oscillator in the flow direction (161, 163), the first and second control ports (160, 162) being disposed on, and in fluid communication with, the outlet nozzle, characterized in that the first control port being defined by the first portion and the outlet nozzle and the second control
