抄録(英) | The aerodynamic characteristics of the evacuated tube transportation system were investigated based on the Reynolds-averaged Navier-Stokes k-w shear-stress transport simulation model in this study. Comparing the two tube train systems with different blockage ratios, i.e., 0.09 and 0.25, the impact of the isentropic limit and Kantrowitz limit on the aerodynamics was explored. Three distinct flow structures were found, which correspond to three speed ranges divided by the critical Mach number of the two limits. The drag of a tube train shows different aerodynamic features under the three speed ranges. 翻訳 |
