Application of CFD for analysis of the ship and propeller flow

Bugalski T. J., Szantyr J.

TASK Quarterly : scientific bulletin of Academic Computer Centre in Gdansk

1998

Vol. 2, No 2

349-356

The paper describes the computer system PANSHIP for analysis of flow around the ship hull moving with constant velocity in calm water, including the effects of free surface and propeller operation. This system calculates the potential flow using the discrete distribution of Rankine sources on the hull. Viscous flow is computed using the integral method in the bow section and Reynolds averaged Navier Stokes equation (RANS) in the stern section of the ship hull. Results of this analysis may be directly used in ship hull design and they may also serve as input for calculation of the unsteady flow phenomena accompanying propeller operation in the non-uniform velocity field generated by the hull. PANSHIP has been verified experimentally and it forms a useful tool available for ship designers and for marine hydrodynamicists.

CTO and SVA joint research project on computation of ship flow phenomena

Bugalski T.J., Abdel-Maksoud M.

Polish Maritime Research

1998

nr 4

9-12

The raport describes results of Ship Design and Research Centre Gdańsk (CTO, Poland) - Schiffbau Versuchanstalt Potsdam (SVA, Germany) joint research project on computations with the use of BOS-L and SHIP-FLOW numerical model basins. The subject of the project was application of CFD methods to studying the phenomena of ship flow. Results of the flow parameter computations for four different ship models (two from CTO and two from SVA) are presented. Some calculation results are compared with experimental data.
