چکیده مقاله:
Ship harmonic motion is an important and practical characteristic in ship design and performance evaluation. The development and optimization of hull-form, ship’s dynamic effects, seakeeping performance, and motion control, all require the motion data that includes wave exciting forces as well as dynamic response of the ship. This paper presents a new approach for time-domain simulation of full-scale ship model with four degrees of freedom based on computational fluid dynamics using unsteady RANS method. The key objective of this paper was the full-scale simulation of ship motion in oblique waves and assessment of time domain forces, moments, and other motion parameters. The David Taylor Model Basin (DTMB) ۵۴۱۵ full-scale model has been used for the numerical studies in this paper. The obtained computational results showed good conformation to the results obtained using the strip theory. It is intended to extend this research to subscale test experiments for more definite validation of the results.
