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

摘要

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 (LW), is presented. The results captured using this unique methodology provide insight into the transient flow around HSTs. (C) 2014 Elsevier Ltd. All rights reserved.
