Computation of Velocity and Pressure Variation Across Axisymmetric Thick Turbulent Stern Flows
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  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.
