AERODYNAMIC AND THERMODYNAMIC VALIDATION TESTS IN THE BERKELEY HILLS TUNNEL. VOLUME II

The report describes the validation of a subway environment simulation (SES) computer program. This validation was done by field test in the Berkeley Hills tunnel of BART. Volume 2 contains the detailed pressure measurements made inside the tunnel, on-board six-car trains and at the tunnel portal. Pressure measurements involve entry and exit transients and pressure fluctuation inside the tunnel caused by both train and emergency fan operations.
