Investigating the Effect of Clearance Distance between the Floor of a High-speed Train and Ground on Aerodynamic Forces in Presence of Side Wind

Abstract: The main objective of this paper was to propose the real model of the high speed train regarding the side wind disturbance. In the first part of this article, the turbulent air flow around a simplified design of a high-speed vehicle was numerically analyzed using finite volume method and four RANS turbulence models, including k-ω SST, k-ε RNG, Spalart-Almaras, and Launder and Sharma. The results of numerical simulations regarding the wall function were validated by experimental works and it was shown that in t… Show more
