Evaluation of the Aerodynamic Effect of a Smooth Rounded Roof on Crosswind Stability of a Train by Wind Tunnel Tests
Abstract
:1. Introduction
2. Methodology: Wind Tunnel Experimental Tests
Experimental Setup
- First car: instrumented with an internal six-component dynamometric balance for measuring forces and moments, and 160 pressure taps placed around the surface of the vehicle;
- Dummy car: placed downstream to reproduce the correct boundary conditions; it corresponds to half of the second vehicle, in compliance with the requirement prescribed by the EN 14067-6 standard.
3. Results
3.1. Aerodynamic Coefficients
3.2. Pressure Distribution
