Aerodynamics of high-speed trains

This review highlights me differences between me aerodynamics or high-speed trains and other types of transportation vehicles. The emphasis is on mode rn, high-speed trains, including magnetic levitation (Maglev) trains. Some of the key differences are derived from the fact that trains operate near t he ground or a track, have much greater length-to-diameter ratios than othe r vehicles, pass close to each other and to trackside structures, are more subject to crosswinds, and operate in tunnels with entry and exit events. T he coverage includes experimental techniques and results and analytical and numerical methods, concentrating on the most recent information available.
