drag coefficient is an important parameter for optimum design of single pole supports. With such an important role played by the drag coefficient, it is critical to know what factors influence the drag coefficient for single pole supports”. From previous studies, the drag coefficient has been shown to be affected by both the shape of the pole and the Reynolds number (Rr^.) . The Reynolds
An important parameter governing the drag coefficient of a body in free-molecule flow is the molecular speed ratio s defined by speed of satellite most probable molecular speecl The most probable molecular sieed vm at any altitude is given by T- , (3) where T is the
Notes: Abstract: A key objective of this study was to experimentally quantify wind load coefficients (drag, torque, and lift) for common bridge girder shapes, and to quantify shielding effects arising from aerodynamic interference between adjacent girders.

  1. The drag coefficients distribution was ascent or descent tendency according to the bed geometry, which showed that the bed length and the bed height were related closely to the flow characteristics.
