Numerical Prediction of Flows over and in the near Wake behind Axisymmetric, Self-Propelled Bodies

Abstract

A technique is presented for the calculation of laminar, transitional and/or turbulent flows over and in the near wake behind bodies of revolution including the effects of separated flow and an operating propeller. The technique uses an interactive boundary-layer program to obtain a viscous solution over a nonseparating body and to provide upstream boundary conditions for a second program which solves the full Navier-Stokes equations for the propeller, separated flow and near wake regions. The results of calculations made using individual elements of, and the complete system of codes were compared with good agreement against both experimental and numerical data and are included in the present work.
