The validated computational fluid dynamics model was then used to study passenger's thermal sensation in a newly designed aircraft cabin at 39,800 ft (12,131 m) cruise height in summer conditions. The convective heat transfer coefficient, predicted mean vote, and predicted percentage dissatisfied on the human body surfaces were analyzed and quantified. Both the measured data and simulation result showed that an approximation of 74.1% of heat loss from the human body surface was caused by convection heat transfer, which means that the ratio between convection and radiation was about 7:3 under the condition of this experiment. In the newly designed aircraft, the two passengers sitting in the aisle ...
