Aerodynamics of high-speed trains with respect to ground simulation

Abstract

The aerodynamics of a simplified 1:20 scale model of the ICE 3 high-speed train are studied. Wind tunnel tests using a stationary and a moving ground were carried out. Changes in drag due to bogie fairings are evaluated for both ground configurations and differences are highlighted. Corresponding numerical simulations using a moving ground were performed. The simulation results agree well with the experimental data.
