Abstract
A device is disclosed that uses a flow-control methodology to control sprays at very high precision and frequency. The device is based on an enhanced Coanda effect. The control flow is selectively applied to the region in which we desire the jet to vector and control the profile (width) of the jet. The control flow is introduced through multiple control flow ports surrounding the primary nozzle and adjacent to the Coanda surface. By selectively opening and closing different control flow ports the motion and profile of the jet can be controlled.
