Numerical Computation for a Flow Caused by a High-Speed Traveling Train and a Stationary Overpass,uantitative agreements were shown in almost cases. Only in the case that the overpass is very close to the train, the effects of boundary layers on laminar flow and turbulence need to be considered for more precise computation.作者: indoctrinate 時間: 2025-3-22 22:12
