Transom Sterns

Transom Stern flows are notoriously difficult for numerical resistance prediction methods to quantify, particularily at low speeds when the hollow is developing. We put Ansys CFX to the test; trying to match some experimental measurements of hollow depth and length. Partially ventilated transom stern from Ansys CFX

The results were effective. Below is a sample of hollow depths and lengths from CFD compared to the experiments. Plot of transom hollow depth comparing CFD result to tank test experiment
