THREE-COMPONENT MEASUREMENTS ON RECTANGULAR WINGS WITH CAVITATION.
Abstract
Investigations of three-dimensional effects in non-cavitating and cavitating flow past rectangular flat plates are reported. Five rectangular wing models with aspect ratios AR = 1.01; 1.5; 2.25; 2.49; and 3.12 were tested. Lift, drag, and pitching moment acting on these models were measured, and the characteristic development of cavities for several flow conditions were photographically recorded. To the extent that measurements of other authors on cavitating hydrofoils were available, these results were used for comparison and supplementation of this work. Values according to the theory of T. Y. Wu (J. Fluid Mech. v13 pt2 p161 1962) about two-dimensional fully cavitating flows were converted into values for a wing with finite aspect ratio and were compared with experimental data. The investigation was performed in a new cavitation tunnel with a free-jet directed vertically upward. Design and performance of the new tunnel are described. (Author)
