Viscous-flow calculations for bare hull DARPA SUBOFF submarine at incidence

International Shipbuilding Progress, 2008
As part of a multi-nation study regarding CFD validation, conducted by the Submarine Hydrodynamics Working Group, viscous-flow calculations on the unappended hull-form of the DARPA SUBOFF sailing straight ahead and at oblique motion were conducted in order to verify the accuracy of the predictions.

Planar motion modeling of full-scale SUBOFF in deep and unlimited water

2019
This paper proposes a numerical approach to predict the planar motion of a full-scale SUBOFF as well as its hydrodynamic coefficients in deep and unlimited water, where the free surface and wall effects are neglected. The Euler’s equations of motions are employed to describe the underwater motion of a body in deep submergence.

Improving the hydrodynamic performance of the SUBOFF bare hull model: a CFD approach

Acta Mechanica Sinica, 2019
The main aims of this study are to investigate the hydrodynamic performance of an autonomous underwater vehicle (AUV), calculate its hydrodynamic coefficients, and consider the flow characteristics of underwater bodies. In addition, three important parts of the SUBOFF bare hull, namely the main body, nose, and tail, are modified and redesigned to ...

Study on Propeller Ingestion Noise in the Wake of the SUBOFF bare hull model

This study numerically investigates the acoustic response of a seven-bladed propeller under the axisymmetric turbulent boundary layer at the stern of the SUBOFF bare hull model, aiming to clarify the noise generation mechanism with focus on the effect of propeller suction on vortex structures.
