摘要：
This investigation builds a 3D model of one real commercial aircraft cabin and uses the Computational Fluid Dynamics (CFD) method to calculate the distribution of the temperature and the velocity in cabin under different individual ventilation temperatures. To verify the reliability of the simulation, this paper compares the simulated and measured temperatures around the position of passenger head. Finally, referring to the average skin temperature of human, this research studies the comfort of passengers under different individual ventilation temperatures. The results show that when the individual ventilation temperature changes, the temperature around the passenger head does not vary much. When the individual ventilation temperature increases from 7℃ to 14℃, the temperature around the head of passenger varies less than 0. 8℃. Different individual ventilation temperatures mildly affect the average skin temperature and thermal comfort of passengers. When the individual ventilation temperature increases from 7℃ to 14℃, the average skin temperature of the target passenger increases by 0.33℃. © 2019, Press of Chinese Journal of Aeronautics.
