Pressure Scale Effects on Shape Drag in a Conduit
Journal of Pipeline Systems Engineering and Practice
While testing cylinders in closed conduit flow, it was found that the drag coefficient varied with pressure at a constant Reynolds number. The conditions at which this phenomenon occurs are presented along with a possible explanation of why it occurs. It is the purpose of the paper to present the problem and to generate ideas and discussion by the readers to help explain the phenomenon
