Abstract

Transom sterns are a common feature on modern ships and boats. At typical cruising speed the flow cleanly separates, ventilates fully, so that the stern is dry. The proper design of a ship requires predictions over the entire speed range, even at lower speeds where the waves downstream collapse and create a partially wet transom. This study combines physical model tank testing, a Reynolds Averaged Navier-Stokes solver, and a medium fidelity potential flow solver, AEGIR, to predict the total resistance of slender, semi-displacement ship. A new method is offered to correct the potential flow solution through the ventilation transition speeds. The use of both high-fidelity RANS and medium-fidelity potential flow solvers are required for practical rapid prototyping of new concepts of for optimal design. The results for the new, corrected potential flow predictions agree well with experiments.
