内容記述 | For the purpose of reducing drag and further speeding up of high-speed train, the axisymmetric Navier-Stokes analyses have been numerically conducted around a bullet train running in depressurized tube. The flows around a simple axisymmetric body, which runs in high subsonic and transonic regimes at velocity more than 500 km/h and freestream pressure 0.001 atm, was solved for various tunnel diameters. When the train speed increases or the diameter of the tunnel decreases, the pressure on the nose tip of the train rises and the separation in the rear part of the train becomes more significant. As a result, the 'drag divergence' phenomena were observed on the plots of the relation between the drag coefficient and the freestream Mach number. The results show that when the tube is depressurized to 0.001 atm, further speeding up becomes possible with smaller power requirement than the existing Shinkansen bullet train. | |||||
