Influence of variable cross-section on pressure transients and unsteady slipstream in a long tunnel when high-speed train passes through
When constructing a long undersea tunnel, cross-sectional area of some parts of the tunnel will be changed to strengthen the tunnel or save construction costs, which will cause a change in aerodynamic characte...
