Abstract

One of the important subjects in aerodynamic design of high speed train is the SLIPSTREAM or air flow around the train. This issue not only waste a significant amount of energy and fuel but also reduce the overall efficiency of the train. Due to irregularity the turbulence air flow around the high speed trains aerodynamic drag, noise and vibration are the most phenomenon that concern in this area. The SLIPSTREAM is one of these aerodynamics features that directily related to the safety of passengers and workers near the line. When high speed train passes near to a standing human body, the produced presuer wave forces on the body surface and may lead to fall. In this numerical simulation we used DYNAMIC MESH method and turbulence equation k-e in computational fluid dynamic software (Fluent). The aim of this study is to investigate the effects of air pressure around the train of moving with 300 km/hr velocity. The pressure waves are calculated in both modes of regular passage and passing with operation of aerodynamic brake. The resules are determined as the safty distance of the passenger from the line due to the different speed.
