Oscillating Flow about Yawed Cylinders.
Abstract
The forces acting on yawed smooth and rough circular cylinders in oscillating flow have been investigated for the purpose of determining the appropriate force-transfer coefficients and the applicability of the 'independence principle.' The results have shown that the flow about each cylinder is unique and the independence principle does not hold true over the range of Reynolds numbers and Keulegan-Carpenter numbers covered by the investigation. It has further been shown that Morison's equation predicts the measured force with the same degree of accuracy as that for the normal cylinder provided that the force-transfer coefficients appropriate to each yaw angle, Reynolds number, Keulegan-Carpenter number, and the relative roughness are used.
