| Abstract: | Based on one-dimensional unsteady compressible non-isentropic flow prediction and the method of characteristics expressed in generalized Riemann Variables, the paper established numerical method and procedures of pressure wave when the high-speed train passed tunnel group between which the space is less than the length of train, and studied the parameter. The presented result provides consultation for later study of this kind of problem. |
