【摘要】 通过试验研究了排风风帽的出风口面积对流动阻力的影响,出风口面积的增大会减小排风风帽的流动阻力,且流动阻力的降低与排风风帽的结构有关。研究结果为机车车辆的排风风帽的设计和改进提供参考。更多还原

【Abstract】 The influnce of exit area of the exhaust cap for locomotive and rolling stock on flow resistance was studied by experiment.Increasing exit area could decrease the flow resistance of the exhaust cap,and the decrease was related to the structure of the exhaust cap.The study result could be used for the design and improvement of the exhaust cap of locomotive and rolling stock.更多还原
