| Abstract: | Using the Couette turbulent flow theory analyses impacts of the air flow between the train and the channel wall on train ventilation effects and proposes a balanced ventilation method to solve the existing problems; the accordingly designed centrifugal ventilation unit into which the air supply and extract are integrated is proved successful in test operation, verifying the value of the proposed method in treatment of ventilation and pressure control of an enclosed space in motion. |
