THEORETICAL AERODYNAMIC CHARACTERISTICS OF VEHICLES IN CONFINED SPACES

The report has been prepared under the Transit Development Corporation (TDC) 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.' It describes the results of a theoretical effort pertaining to the non-steady flow in a tunnel induced by a moving vehicle. A study is made of the entry problem and the problem of a vented tube.
