SUBWAY AERODYNAMIC AND THERMODYNAMIC TESTS

The purpose of this 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 0.35 and 0.75 is described for steady and unsteady runs. Comparison with the CalTech theoretical work is made.
