<p>An air outlet for a passenger compartment of a vehicle has a duct forming a jet of air, a pair of lateral sidewalls (10), bounded by the top (T) and bottom (B) walls, diverging (12, 13, 15, 16 and 17) from each other from their upstream ends to their downstream ends at a rate sufficient to preclude a stable wall effect and for causing aperiodic oscillation of the jet into the passenger compartment of said vehicle. Various means (21, 22, 25, 31, 32 and 35) are disclosed to further destabilize the wall effect.</p> |
