Moving model analysis of the slipstream and wake of a high-speed train

A scaled moving model technique for analysing the slipstream of a high-speed train (HST) with the view of applying this methodology for checking TSI compliance in the design phase of a HST is assessed. Results from experiments are compared to full-scale field test results, and the sensitivity of slipstream to two of the limitations of scaled testing, Reynolds number and the length to height ratio (L/H), is presented. The results captured using this unique methodology provide insight into the transient flow around HSTs.
