    Nonlinear spatiotemporal characteristics of wind–rain flow around the trains passing through the tunnel entrance during rainstorms

    Tropical storms present a significant risk to the safety of high-speed trains due to the extreme wind and rainfall they bring. This study employs Eulerian multiphase and Shear-Stress Transport k-ω turbulence mode...
