Subway Aerodynamic and Thermodynamic Test (SAT) Facility -Double Track Aerodynamics.

摘要

The report is one of many leading to the final product, a 'Subway Environmental Design Handbook'. The purpose of the report is to present,describe and interpret the test data generated in the SAT Facility (double track,rectangular cross section tunnel,smooth,with a solid dividing wall, 15% porosity curtain wall and open except for periodic columns. In particular,aerodynamic data for 3trains of blockage ratios varying between .35and .75are described for steady and unsteady runs.
