THE AERODYNAMIC ANALYSIS OF SINGLE AND MULTIPLE VEHICLES ENTERING AND TRAVELING IN OPEN TUNNELS

The analyses required to calculate the aerodynamic effects of tunnel entry, tunnel venting and multiple vehicle motions in open ended tunnels are presented. Results for several cases of open ended tunnel travel and various entry configurations are presented and described. The effects of an earlier vehicle's motion on the pressure peak associated with a second vehicle entering a tunnel are presented and discussed.
