ANALYSIS OF THE NEAR FLOW FIELD FOR TUBE-VEHICLE SYSTEMS

Results are presented from the investigation of vehicle drag in tube transportation systems. The report emphasizes the analysis of the aerodynamic phenomena in tube vehicle systems. A simplified one-dimensional analysis is formulated for the near flow field. The analysis is applied to several model vehicles, and the results compared with existing data from 19 different experiments. The correlation between the experimental and analytical drag coefficients is good. Also, the dependence of the drag coefficient on various flow parameters is examined and tentative conclusions presented. (Author)
