AERODYNAMIC NEAR FIELD OF A SUBWAY TRAIN IN SMOOTH AND ROUGH TUNNELS

The report has been prepared under Transit Development Corporation 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. A theoretical model for the near field aerodynamics of a subway train in smooth and ribbed tunnels has been developed. The theoretical results have been compared with experimental data measured in a number of different facilities over a wide range of experimental conditions.
