WebJan 17, 2024 · The train aerodynamic drag consists of pressure drag and viscous drag. Because the length-to-width ratio of a train ranges from 50~100, which is much larger than that of any other ground vehicle, the aerodynamic characteristics are more complex than those of cars, trucks or airplanes [ 11 – 13 ]. WebOct 3, 2014 · We newly introduce lift force into the aerodynamics of dust grains in a protoplanetary disk. Although many authors have investigated the effects of the drag force, gravitational force, and electric force on the dust grains, the lift force has never been considered as a force exerted on dust grains in a gas disk.
