Abstract: The air discharge device includes a duct defining: a main flow path through which an air flow passes; and a main hole opened in a flat shape to discharge the air flow as a working air flow toward a downstream from the main flow path. A throttle portion is provided in the duct to reduce a flow path height of the main flow path from an upstream of the air flow toward a downstream of the air flow. A plurality of partitions are arranged to divide the main flow path in a major direction into a pair of side flow paths and at least one center flow path. The plurality of partitions are disposed in the duct such that a flow path width of the center flow path is reduced from the upstream of the air flow toward the downstream of the air flow.

Abstract: An air blowing device includes a duct portion and a passage variable device. The duct portion forms a main passage through which an air flow passes, and an outlet is defined downstream of the main passage to blow out the air flow. The passage variable device is configured to change a passage area of the main passage so that the air flow becomes a pulsating flow and is blown out from the outlet.

Abstract: An air discharge device is configured to discharge an air flow. The air discharge device includes a main hole for discharging an air flow as a working air flow, an auxiliary hole provided around the main hole to discharge a support air flow, and a vortex suppression structure configured to suppress development of vortices generated in a velocity boundary layer of the working air flow at a downstream side of an outlet of the main hole. This vortex suppression structure is configured to make a central portion of the thickness of the velocity boundary layer of the working air flow at the downstream side of the outlet of the main hole to be closer to a mainstream of the support air flow, at the downstream side of the outlet of the main hole.
