Abstract

Based on the one-dimensional unsteady compressible non-isentropic flow theory and round-piston radiation theory with infinite baffle plate, the aerodynamic effects generated by a high-speed train through a tunnel with the discontinuous-type hood were numerically investigated, which shows the discontinuous-type hood can attenuate the pressure transition in tunnel and micro-pressure wave intensity around the tunnel exit. That analysis of the hood parameters show the larger cross-section area and the short length of hood with the short binding site length attenuate the aerodynamic effects effectively.
