Abstract

Many propellers and appendages are located inside of ship stern boundary layers. Therefore, it is essential for naval designers to obtain a fundamental understanding and accurate predictions of this special class of external thick turbulent stern flows. A series of experiments has been conducted at David W. Taylor Naval Ship R & D Center to determine the unique turbulence structure and viscous-inviscid interaction of thick axisymmetric [526–529] and simple three-dimensional [530–532] stern flows. The Lighthill [533] displacementbody concept has been proven experimentally to be an accurate approach for computing viscous-inviscid stern flow interaction. The measured static pressure distributions on the body and across the entire boundary layers were predicted by the displacement-body method to an accuracy within one percent of dynamic pressure.
