Abstract: At present, some automobile models circulating in the market are prone to ear pressure and discomfort when the door is closed. During the door closing process, the gas in the cabin cannot be effectively discharged, resulting in a pressure difference inside and outside the cabin. There is little research on this phenomenon at home and abroad. Therefore, this paper uses the overlapping grid method in fluent software to monitor the position of the human ear during the door closing process through simulation, obtaines the pressure change curve at the monitoring point, analyzes the flow field, then obtaines the pressure change trend at the human ear and the flow field characteristics in the calculation domain.

Key words: Door closing process; Ear pressure sensation; Overlapping grid; Flow field characteristics
