The purpose of the paper is to derive variation law of aerodynamic drag introduced by high-speed train passing through a tunnel and to offer guidance for design of high-speed railway longitudinal section and high-speed train head shape. The paper presents a cell-centered finite volume scheme for numerical integration of Navier-Stokes equations for three-dimensional unsteady viscous compressible nonhomentropic flow to simulate the aerodynamic drag introduced by high-speed train passing through a tunnel. The aerodynamic drag curve is analysed and explained in detail in accord with the train positions
