ABSTRACT

Computational fluid dynamics (CFD) techniques are improving and now are frequently used to augment, and occasionally replace, physical experiments. In this paper, the free surface viscous flow around a bare hull model is simulated with two CFD software (FINE Marine, a CFD product of NUMECA and ANSYS CFD) and compared to the results obtained during the experimental tests. The bare hull model studied in this paper is DTC (Duisburg Test Case), a typical 14000 TEU container ship, developed at the Institute of Ship Technology, Ocean Engineering and Transport Systems (ISMT) for benchmarking and validation of the numerical methods. Regarding the solution obtained, it can be noticed a satisfactory agreement between towing test results and the computation results. Comparative to NUMECA analysis, where the mean difference over the speed domain between model test and numerical simulation is about 2.16%, for ANSYS case, the medium percentage difference is 2.98%.
