Abstract
A fluidic oscillator includes a vortex chamber in fluid communication with a flow volume, an outlet, a first control port, and a second control port. The flow volume is defined by a first wall and a second wall. The first wall and the second wall are arranged to direct a fluid flow to create a vortex flow in the vortex chamber. The pressure differential cycles the attachment of fluid flow between the first wall and the second wall at a cycle rate. Because the fluidic oscillator can operate at a low cycle rate, the fluidic oscillator can provide an extended reach.
