VENT AND STATION TEST (VST) FACILITY CHICAGO TRANSIT AUTHORITY SCALE MODEL VENT SHAFT TESTING

The purpose of this report is to present, describe, and interpret experimental data generated in the Vent and Station Test (VST) facility for a 1:16 scale model vent shaft typical of the Chicago Transit Authority (Kennedy Branch) subway system. Data obtained from the model testing were compared to calculations using semi-empirical formulations of vent shaft performance. This research was conducted under the Institute for Rapid Transit project, 'Ventilation and Environmental Control in Subway Rapid Transit Systems,' and is one of many such reports leading to the final product, a 'Subway Environmental Design Handbook.' The report describes both 'straight-through' and 'in-situ' tests; complete statistical data are appended. (Author)
