Abstract:

In order to supplement the limited data so far discovered, the evaluation of the drag coefficients of various head forms under cavitating conditions at various angles of yaw, from the measured values of the pressure distribution, was undertaken. The aforementioned pressure distributions for zero angle of yaw were published by the Iowa Institute of Hydraulic Research, in 1948. Eight of the head forms included in these first tests were selected for a further study of pressure distribution under cavitating conditions at angles of yaw and the results were published in 1962. The latter also included pressure distribution measurements at zero angle of yaw. The results obtained for the drag coefficients of the various head forms at several yaw angles are presented and compared with the directly measured values for the drag at zero angle of yaw available in the literature. No data on direct measurements of drag at angles of yaw have been found.
