Experimental and Numerical Study of Gasper-Induced Airflow in an Aircraft Cabin Mockup

摘要

The air distribution in commercial airliner cabins is crucial for creating a thermally comfortable and healthy cabin environment. Gaspers are prevalently installed as a personalized ventilation system in aircraft cabins in order to improve cabin thermal environment. However, there are few studies investigating the air distribution in a cabin with gaspers on. This study first conducted experimental measurements of gasper-induced airflow field by Particle Image Velocimetry (PIV) in a half of a full-scale, one-row, single-aisle aircraft cabin mockup. This investigation then used the measured data to evaluate the RNG k-s model, which was superior for the main airflow, and the SST k-ω model, which can predict better jet flow. Overall, the results showed that the SST k-ω model was more accurate than the RNG k-ε model for predicting the gasper-induced airflow in an aircraft cabin. However, in the other regions, both the RNG k-ε and SST k-ω models had similar performance. Thus, the SST k-ω model was more suitable model for predicting gasper-induced airflow in aircraft cabins.
