The invention relates to a method for reducing air resistance on the surface of a high-speed train, which comprises the following steps of: forming a layer of fluid film on the outer surface of a carriage of the high-speed train by utilizing a 'smearing' effect of external air passing through the high-speed train on fluid flowing out of the outer surface of the carriage from the inside of the train, so that the outer surface of the carriage of the high-speed train is isolated from the external air, therefore, air resistance on the surface of the high-speed train is reduced. The invention further provides a device for reducing the air resistance on the surface of the high-speed train. A layer of fluid film is formed on the outer surface of the carriage of the high-speed train, so that the carriage is isolated from outside air, and the viscous resistance of the outside air to the outer surface of the carriage is greatly reduced.
本发明涉及一种减少高速列车表面空气阻力的方法,利用高速列车所正穿过的外界空气对自列车内部流出车厢外表面的流体的“涂抹”作用,在高速列车的车厢外表面形成一层流体膜,使得高速列车的车厢外表面与外界空气隔离开来,从而减少高速列车表面的空气阻力。本发明还提供了一种减少高速列车表面空气阻力的装置。通过在高速列车车厢外表面形成一层流体膜,使得车厢与外界空气隔离开来,极大地降低了外界空气对车厢外表面的粘滞阻力。
