The evolution of coronavirus disease (COVID-19) into a pandemic has severely hampered the usage of public transit systems. In a post-COVID-19 world, we may see an increased reliance on autonomous cars and personal rapid transit (PRT) systems, with inherent physical distancing, over buses, trains and aircraft for intracity, intercity, and interstate travel. However, air travel would continue to be the dominant mode of intercontinental transportation for humans. In this study, we perform a comprehensive computational analysis, using ANSYS Fluent, of typical intercontinental aircraft ventilation systems to determine the seat where environmental factors are most conducive to human comfort with regards to air quality, protection from orally or nasally released pollutants such as CO₂ and coronavirus, and thermal comfort levels. Air velocity, temperature, and air pollutant concentration emitted from the nose/mouth of fellow travelers are considered for both Boeing and Airbus planes. In each plane, first class, business class, and economy class sections were analyzed. We present conclusions as to which is the optimum seat in each section of each plane and provide the data of the environmental conditions to support our inferences. The findings may be used by the general public to decide which seat to occupy for their next intercontinental flight. Alternatively, the commercial airliners can use such a model to plan the occupancy of the aircraft on long-duration intercontinental flights (viz., Airbus A380 and Boeing B747).

冠状病毒病 (COVID-19) 演变成大流行病严重阻碍了公共交通系统的使用。在 COVID-19 之后的世界中，我们可能会看到对自动驾驶汽车和个人快速交通 (PRT) 系统的依赖增加，这些系统具有内在的物理距离，在公共汽车、火车和飞机上进行城内、城际和州际旅行。然而，航空旅行将继续成为人类洲际交通的主要方式。在这项研究中，我们使用 ANSYS Fluent 对典型的洲际飞机通风系统进行了全面的计算分析，以确定在空气质量、防止经口或鼻腔释放的污染物（如 CO）方面环境因素最有利于人类舒适的座位。₂和冠状病毒，以及热舒适度。波音和空中客车飞机都考虑了从同行旅客的鼻子/嘴巴排放的空气速度、温度和空气污染物浓度。在每架飞机上，都对头等舱、商务舱和经济舱部分进行了分析。我们就每架飞机的每个部分的最佳座位提出结论，并提供环境条件数据来支持我们的推论。公众可以使用调查结果来决定下一次洲际航班的座位。或者，商业客机可以使用这种模型来计划飞机在长期洲际航班（即空中客车 A380 和波音 B747）上的占用。
