Abstract

Abstract

A drag-reduction technique based on boundary layer control was proposed to reduce the aerodynamic drag during the operation of high-speed train.Taking CRH3 as an example, the turbulence characteristics of boundary layer was controlled by mounting ball sockets non-smooth surface on the surface of vehicle body to achieve train's drag reduction.The models of high-speed train, parametric ball socket and computational domain were established by means of PRO/Engineer software, and the body model of high-speed train was simplified without any impact to the research effect in order to reduce numerical simulation computing cycle.The non-structure grid partition of computed field was carried out by ICEM CFD software to enable the grids to better fit in with streamlined body and ball sockets non-smooth surface.In consideration of the effect of train's surface roughness on the aerodynamic drag, the k-ε turbulence model incommercial fluid software FLUENT was applied to conduct numerical simulation analysis of outside flow field in open air at the running speed of 300 km·h^-1.Simulation result shows that only placing the ball sockets non-smooth surface on the tail of train is more conducive to reduce the aerodynamic drag.Train's aerodynamic drag first decreases and then increases with the increase of the radius, depth and array distance of ball sockets.When the ball socket non-smooth surface is placed on the tail of train, and the array distance, radius and depth of ball sockets are 350, 80 and 10 mm, respectively, the drag reduction effect is best.The aerodynamic drag for the ball socket non-smooth surface is 2 220.4Ncompared to 2 967.9N without placing ball sockets, so the drag reduction rate is up to 25.19%.Obviously, using ball sockets non-smooth surface to change the turbulence characteristics of boundary layer is an effective way to reduce train's aerodynamic drag.
