Turbulent characteristics in the near fields of gasper jet flows in an aircraft cabin environment: Intermittently energetic coherent structures

Recent progress on studies of airborne infectious disease transmission, air quality, and thermal comfort in the airliner cabin air environment

“…The airflow from a gasper is complex. Tang et al 113 measured gasper flow with a high‐frequency hot‐wire anemometer and found that the mean velocity, velocity gradient, and energy spectra in the near fields of jet flows depended on nozzle geometry, and beyond the attachment point the flow exhibited self‐similarity. On the contrary, it is not easy to predict airflow from a gasper.…”

Experimental study of the impact of passenger behavior on the aircraft cabin environment

“…Due to the interaction of the gasper-induced jet and the main ventilation in the cabin, a clear vortex structure is formed near the gasperinduced jet (You et al 2016). The gasper jet fields are dominated by intermittently energetic coherent structures (Tang et al 2017). According to airflow research of , they evaluated the influence of the gasper jet on the main ventilation using an experimental study.…”
