“…63% of the passengers used the gaspers during the flight [22]. Fang et al [23] also found that more than half of the occupants opened the gasper to alleviate stuffiness. Therefore, to investigate the air distribution in an airliner cabin, the influence of the air from gaspers on the cabin environment needs to be clarified.…”

“…However, in practice, passengers usually turn on these nozzles to achieve preferred environment after boarding the aircraft. 25–28 In order to study the characteristics of jet flow from aircraft nozzles, Fang et al. 25 analysed the jet pattern of the gasper in a three-row seat mock cabin.…”

“…Later, Fang et al. 27 analysed the variation in the subjective thermal reaction and regular utilization of nozzles by stimulation investigation of passengers and their procedure from boarding to taking their seating. The results indicated that under different attendance rates, over 50% of subjects adjusted the personnel nozzle to satisfy the thermal comfort of their upper body due to a ‘muggy sensation’.…”

For investigating the thermal comfort impact of supply air from personal nozzles on body positions of human bodies in aircraft cabins, a mock aircraft cabin with three rows of seats was built to investigate the effect of personal nozzle on thermal comfort of three main body parts, including head, upper body and lower body. In total, 12 tests were performed on 16 volunteers. Every test lasted 3 h and 40 minutes. Simultaneously, volunteers’ responses for both local and overall thermal responses were recorded. Skin temperatures were monitored. The results showed that when cooling the upper body, variation in local thermal sensation, overall thermal sensation and average skin temperature were the most significant responses produced by 16 young healthy human volunteers taking part in the experiment. However, for the airflow sensation, the strongest impact was at the head (including forehead and face), followed by the upper body part (breast, back, shoulder, abdomen) and then the lower body part (buttock, sex organ, thighs, legs and feet). In order to minimize draft discomfort, the air supply from nozzles should be delivered directly to the upper body, which would make the passengers more comfortable and benefit the optimization of the design of the nozzle.

“…More than 60% of passengers advocated that it was necessary to utilize the gasper (Personal ventilation nozzle) (Fang et al 2018). The gasper has an overhead influence on an individual's upper body thermal comfort in aircraft cabins (Fang et al 2015, Fang et al 2019. 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).…”
