Slipstream Experiment Setup

Abstract

This chapter describes the experiment setup and methodology adopted for the slipstream development research. Section 2.1 introduces the model scale slipstream experiment design and methodology undertaken at the TRAIN rig facility; outlining the facility features in Sect. 2.1.1 and the motivation and development of the model design in Sect. 2.1.2. Section 2.1.3.1 defines the coordinate system used for both model and full scale experiments. The model scale trackside instrumentation, including measuring probes, position finders and ambient condition monitors are described in Sect. 2.1.3.2 and the experiment methodology is discussed in Sect. 2.1.4. Similarly Sect. 2.2 discusses the full scale experiment design and methodology undertaken at Uffington. The Uffington test site is introduced in Sect. 2.2.1, and previous Uffington research carried out is discussed in relation to site suitability for slipstream experiments. Sections 2.2.2 and 2.2.3 describe the full scale experiment setup, including trackside instrumentation, and the experiment methodology respectively. Section 2.2.4 gives an overview of all the trains which passed the test site during the experiment and how specific trains have been chosen for this study.
