INFLUENCE OF WATER DEPTH ON SHIP STERN FLOWS

A method for computation of turbulent ship flow is applied to study the influence of shallow water on the flow around a slender ship hull. The Reynolds-averaged Navier-Stokes Equations for incompressible flow are solved in a finite-volume approach on a nonorthogonal, body-fitted, structured grid. Turbulent stresses are modified by an algebraic eddy viscosity model. The free surface is replaced by a plane of symmetry. Results for a Series-60 ship model with CB = 0.6 moving steadily ahead in shallow and deep water agree well with experiments in most respects. Differences can be explained by the neglected free surface, dynamic sinkage and trim.
