Optimization of passenger individual air nozzles

Modern commercial aircraft have sophisticated systems to provide a save, healthy and comfortable environment for the passengers. These systems mostly operate invisible in the background, but the passengers can exert also direct control over their individual thermal environment by adjusting the air flow provided by nozzles in the overhead stowage compartment. Being only an optional system, the individual air nozzles received not much attention in the past and feature a high pressure loss, which are also a cause for flow noise. A significant simplification and weight reduction of the individual air distribution system will be possible, once the pressure loss of the nozzle is being reduced. The objective of this optimization work is therefore to minimize the pressure loss of an individual air distribution nozzle while maintaining it main function – the cooling effect perceived by the passenger. CATIA was used to create a parametric CAD model while STAR-CCM+® and Optimate+ were used to perform the simulation and design exploration respectively.
