Numerical Hydrodynamics. Software for Propulsors

Program package PUF-3A.

The main hydrodynamic programs are developed in Massachusetts Institute of Technology and University of Texas at Austin. In collaboration with CEHIPAR within a Consortium on high-speed propellers.

Applications

• Hydrodynamic analysis of propellers.
• Auxiliary tool for design of propellers.
• Calculation of steady and unsteady (6 components) forces and efficiency.
• Pressure distribution calculation on both sides of propeller blades.
• Sheet cavity forms prediction.
• Prediction of pressure fluctuations on the stern of the ship.

The package comprises the following principle programs:

• MPUF-3A. Validated lifting-surface code for forces and cavitation prediction.
• PROPCAV. Panel (boundary element) method for forces and cavitation prediction.
• HULLFPP. Pressure fluctuations on the stern of the hull due to the propeller.
• GBFLOW. Effective wake prediction, including complex propulsors such as ducted-propellers and pods.
• PROPRE. Preprocessor of propulsor geometry, wake and parametric data.
• PROPOS. Postprocessor for numerical and graphical output.
