AIR OUTLET WITH APERIODIC OSCILLATION

摘要

A air outlet for a passenger compartment of a vehicle has a duct forming a jet of air, a pair of lateral sidewalls, bounded by the top and bottom walls diverging 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 are disclosed to further destabilize the wall effect.
