Paper Title:
The one-Dimensional Unsteady Flow Prediction Method for Pressure Waves in High-Speed Subway and its Applications
  Abstract

With the speed-up of subway, the discomfort problem of passengers caused by pressure waves becomes more and more serious. The prediction method of the pressure waves based on the one-dimensional unsteady compressible non-homentropic flow model and the method of characteristics is introduced, and the program is developed which can be used to calculate the pressure waves not only produced by single train passing through subway tunnel with airshafts, but also produced when the train starts or stops. On this base, the influence of the train speed and the cross-section area of airshafts to the comfort of passengers in the subway is researched. All these work provides the foundation for the development of the one-dimensional unsteady flow prediction method for pressure waves produced by the train passing through subway tunnel.
