Slipstream Control for High-Speed Trains

This thesis examines a variety of techniques for reducing the slipstream velocities experienced by passengers located in proximity to a passing high-speed train. Using a detailed computational model, 83 different designs are explored, and their effect on the flow around the vehicle catalogued. It was established that many of the designs, including physical surface additions, flow injection vents and flow suction regions were capable of significant slipstream velocity reductions, and thus improved passenger safety.
