The influence of air duct geometry on air jet direction in aircraft cabin ventilated by mixing ventilation

Abstract

The paper deals with investigation of influence of air duct geometry on air jet direction in aircraft cabin ventilated by mixing ventilation. CFD approach was used for investigation and model geometry was based on small aircraft cabin mock-up geometry. Model was also equipped by nine seats and five manikins that represent passengers. The air jet direction was observed for selected ambient environment parameters and several types of air duct geometry and influence of main air duct geometry on jets direction is discussed. The model was created in StarCCM+ ver. 6.04.014 software and polyhedral mesh was used.The paper deals with investigation of influence of air duct geometry on air jet direction in aircraft cabin ventilated by mixing ventilation.
