Experimental study of the aerodynamic countermeasures for reducing the micro-pressure waves and pressure fluctuations in high-speed train-tunnel interfaces

The test facility of the 1/60-scale models for the train-tunnel interactions was developed to investigate the effects of entry portal shapes, hood shapes and airshafts for reducing the micro pressure waves radiating to the surroundings of the tunnel exits. In the operation of our test facility, the speed of train...
