SUBWAY AERODYNAMIC AND THERMODYNAMIC TEST (SAT) FACILITY - DOUBLE TRACK AERODYNAMICS

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 3 trains of blockage ratios varying between .35 and .75 are described for steady and unsteady runs.
