摘要: Abstract Enhanced soiling is frequently observed near the multi-slot cabin supply air nozzles in twin-aisle commercial airplanes, which would increase cleaning and maintenance costs. This study proposed a computer-aided design approach to develop new nozzle for reducing particle deposition airplanes. In nozzle, slot dividers were removed reduce deposition, while shape of plenum was re-designed using computational fluid dynamics (CFD) ensure uniformity. The fabricated 3D printing technique. performance compared with that original by both experimental measurements numerical simulations, terms velocity distribution, pressure drop, noise level, weight. results show can significantly on target surface comparison nozzles, providing similar airflow temperature distributions aircraft cabin. Furthermore, exhibited better uniformity, lower lighter weight than nozzles.
