Abstract: A fluid flow system of the present invention includes a supply source for conditioning a flow of fluid and a plurality of ducts for delivering the conditioned fluid to a passenger compartment of a vehicle. One of the ducts is a discharge device having an outer peripheral wall and a flow distribution assembly. The outer peripheral wall and the flow distribution assembly are configured to improve a distribution of the fluid to the passenger compartment. The flow distribution assembly includes a plurality of plates having various thicknesses and flow paths of different sizes and spacing formed therein to direct and substantially uniform distribute the fluid, maximizing a performance and an efficiency of the fluid flow system.
