Abstract

An indirect formulation of the Boundary Element Method is developed to predict the aerodynamic loads on an idealized railway train model in a cross-wind at large yaw angles up to 90°. This is a combined two- and three-dimensional procedure in which a 2-D calculation simplifies dramatically the computation required for the 3-D calculation. The results compare positively with experiments.
