Abstract

The slipstream of freight trains was investigated using two experimental aerodynamic methodologies: a scaled wind-tunnel and scaled moving-model. Both experimental methodologies identified the large effect loading configuration can have on slipstream, with container sized gaps having the largest effect, whilst wagon-wagon sized gaps were also identified as having potential for optimisation. Gap order was also identified as having an influence. Additional insight into the cause of the peak slipstream was achieved with flow field measurements using particle image velocimetry.
