Abstract

Measurements on a large circular cylinder in a pressurized wind tunnel at Reynolds numbers from 10^6 to 10^7 reveal a high Reynolds number transition in which the drag coefficient increases from its low supercritical value to a value 0.7 at R = 3.5 × 10^6 and then becomes constant. Also, for R > 3.5 × 10^6, definite vortex shedding occurs, with Strouhal number 0.27.

Additional Information:Copyright © 1961 Cambridge University Press. (Received 15 November 1960) We are indebted to the many people whose co-operation made this ‘crash program’ possible. The wind tunnel time was donated by the CWT owner companies, crews of the Guggenheim Aeronautical Laboratory and CWT assisted with the experiments, and the Fluid Mechanics group of the Jet Propulsion Laboratory provided instrumentation. David Russell and Dorothy Diamond assisted with the experiments and the computations, respectively.
