Surface Pressure on the Noise Absorbing Board of High-Speed Railway Track

Taking Cheng-Guan railway as an example, the compressible Navier-Stokes equations and k-E turbulent model is used to build a three-dimensional computational fluid dynamics (CFD) model to research the pressure distribution on noise absorbing board surface using numerical methods. The maximum negative pressure is given at different train speeds and noise absorbing thickness. The research results in this paper can be a reference to the design of absorbing board for high-speed railway.
