A Computational of benchmark model of resistance test at Indonesian Hydrodynamic Laboratory

Abstract

Abstract Benchmarking are the activity of comparison of different methods, procedures, physical models to obtain the same target in order to achieve a better standard of performance and exercises provide a common basis for validation of numerical methods. The work develops on prior studies into benchmarks and uncertainty analysis for ship model resistance tests of LHI-007 was used for benchmark testing from 2010 to 2020 at the Indonesian Hydrodynamic Laboratory. A computational study based on the free-surface capturing approach performed with the FINE/Marine flow solver to predicted total resistance in calm water of four speed (1.63 m/s - 2.47 m/s). Verification and validation method studied uncertainty analysis for both for experimental and computational following the ITTC guidelines. The results show comparison between computed results and previous published experimental tests of total resistance (R T ) and coefficient total resistance (C T ) are done to validated CFD simulations. The result of this study concludes that predicted resistance of the benchmark model has reasonable accuracy that the present solver.
