Extract

Measurements of cylinder drag in two-dimensional flow are readily available. In contrast, drag data for other cylinder configurations in which the flow is not strictly two-dimensional, for example free-ended cylinders or cylinders joined to a plane wall, is less plentiful. Some results for the former case have been given by Wiesels-berger and others, obtained at Gottingen and NPL, have been presented by Goldstein.

This note discusses some preliminary drag measurements made for turbulent flow about circular cylinders which were joined to plane parallel walls at each end. Such configurations appear repeatedly in practice. The justification for applying the classical free-ended cylinder data to this problem is slight since, in this case, flow may occur round the ends of the cylinder from the high pressure region upstream to the low pressure wake.
