Purposes


The purposes of the workshop are to assess the state of the art in computations of viscous flows around a ship hull and to accelerate research and development of numerical ship hydrodynamics. These purposes are inherited from the preceding workshops in 1980, 1990, 1994 and 2000.


Recommendations of the previous workshop, Gothenburg 2000, are summarized as follows:
-Similar workshops should be conducted about every five years.
-Modern ship hull forms should be used as test cases.
-Surface streamlines and pressure distributions together with turbulence quantities should be analyzed in detail.
-Propeller-hull interaction, effect of drift angle and the forward speed diffraction problem should be considered for additional cases.
-Standard methodology for verification and validation for CFD methods and their solutions should be used.


The present workshop aims at providing the marine CFD community with an opportunity to assess some of the above issues. The ship hull forms are the same as the ones used in Gothenburg 2000, but, reflecting the expanding need for CFD, in addition to the conventional subjects of resistance and self-propulsion, maneuvering (oblique motion) and sea-keeping (diffraction) simulations are considered as the new test cases. Resistance estimation with trim and sinkage free condition is also added. New experiments are planned to obtain additional data and towing-tank research community is invited to contribute to EFD validation database, including rigorous uncertainty analysis (contact the organizers for detail). Toward the establishment of verification and validation procedure, a grid dependence test using the common grids with different grid densities is also planned, which will enable the direct comparison of the characteristics of the different methods. Further, using statistical analysis of the collected data, we will discuss issues of code certification.
