REVIEW OF AERODYNAMIC INVESTIGATIONS FOR HIGH SPEED TRAIN

With the fast development of the domestic high speed railway, the very high running velocity of the trains causes a series of aerodynamic problems, including the problems of the aerodynamic drag, the cross wind effect, the train passing effect, the tunnel effect and the aerodynamic noise. It is very important to combine various investigation technologies, such as the model testing, the real train measurements and the numerical simulation to study the aerodynamics of the high speed train. This paper reviews the domestic and overseas aerodynamics studies of the high speed train, and the development directions.
