# Experiments on the flow past a circular cylinder at very high Reynolds number

@article{Roshko1961ExperimentsOT, title={Experiments on the flow past a circular cylinder at very high Reynolds number}, author={Anatol Roshko}, journal={Journal of Fluid Mechanics}, year={1961}, volume={10}, pages={345 - 356} }

Measurements on a large circular cylinder in a pressurized wind tunnel at Reynolds numbers from 106 to 107 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 × 106 and then becomes constant. Also, for R > 3.5 × 106, definite vortex shedding occurs, with Strouhal number 0.27.
