<p>A jet excitation system (10) includes a pulsator mechanism (20) positioned in a fluid delivery duct (12) upstream from a nozzle. The pulsator mechanism (20) imparts periodic pressure pulsations to a fluid stream in a manner than enhances spreading and increases entrainment and mixing of the jet (60) exiting the nozzle. The jet excitation system (10) when employed in heating, ventilation and air condition (HVAC) systems increases the entrainment, mixing and spreading of an air stream exiting a nozzle into an enclosure.</p> |
