Abstract The performances of high-speed trains in the presence of coupling effects with
crosswind and rain have attracted great attention in recent years. The objective of the
present paper was to investigate the aerodynamic characteristics of a high-speed train under
such conditions in the framework of an Eulerian-Lagrangian approach. An aerodynamic
model of a high-speed train was first set up, and the side force coefficient obtained from
numerical simulation was compared with that provided by wind tunnel experiments to
verify the accuracy of the approach. Then, the effects of the yaw angle, the resultant wind
speed, and the rainfall rate on… More >
