Evaluation of Resistance, Sinkage and Trim, Self Propulsion and Wave Pattern Predictions,s. It is found that for grid sizes larger than 3M cells all submissions are within 4?% of the measured data. The mean comparison error (data-simulation) is only ?0.1?% and the mean standard deviation is 2.1?% of the data value, excluding self-propelled cases for which the error is larger.

Additional Data for Resistance, Sinkage and Trim,with the original data used at the Workshop. The purpose is to provide additional information useful for future validation of CFD results and to estimate the uncertainty in the data from the different facilities. However, due to lack of information about precision in most measurements only bias erro作者: Ostrich 時間: 2025-3-23 03:46 作者: 土坯 時間: 2025-3-23 07:54 作者: 作嘔 時間: 2025-3-23 10:59
Introduction, Conclusions and Recommendations,ons requested from the participants are specified. Based on a questionnaire sent to all participants the details of their CFD methods are listed, and finally the general conclusions and recommendation for future Workshops are presented. The detailed results of the computations are discussed in subsequent Chapters.作者: MOAN 時間: 2025-3-23 16:39
Evaluation of Local Flow Predictions,f modern CFD methodologies. For resistance and hull/propeller coupling configurations, a detailed comparison of the best statistical turbulence models and LES or hybrid LES turbulence closures, introduced for the first time in this workshop, is conducted to identify their respective impact on local flow simulations.作者: 裂隙 時間: 2025-3-23 19:14 作者: Morbid 時間: 2025-3-23 23:02

Evaluation of Seakeeping Predictions,. Compared with potential flow, CFD showed larger errors for motions for the medium and long wavelengths. For wave diffraction submissions, the large grid size DES simulation has achieved an average error value of less than 10?%D, while for the small grid size URANS simulations the average error is 作者: 揮舞 時間: 2025-3-25 13:58
A Verification and Validation Study Based on Resistance Submissions,g the research groups. In the study of structured grids using different verification methods, most solutions achieve monotonic convergence and are in the vicinity of the asymptotic range. Similar uncertainties are then predicted by the three methods. For cases further from the asymptotic range the m作者: Condescending 時間: 2025-3-25 18:56
