عنوان انگلیسی Investigation of the motions and added resistance of dhow vessel in regular head waves using CFD method
چکیده انگلیسی مقاله Dhow vessels are among the earliest traditional vessels employed for fishing and transporting goods in some countries around the Indian Ocean and Persian Gulf for many years. So far, no research has been done on the hydrodynamics and resistance of these vessels, and the body form of these vessels has been designed in a totally classical and experimental way. One of the most critical issues in the hydrodynamic design and safety of vessels is the added resistance to waves. In this research, the effect of different waves on the hydrodynamic resistance of a dhow vessel has been numerically investigated. The numerical method used in this research is computational fluid dynamics, and StarCCM software was used for this purpose. KCS model results were used to validate CFD results, and finally, the added resistance of the dhow vessel in waves with different lengths and 3 wave heights was investigated. Results show that at short and long wavelengths, the added resistance is lower than at moderate wavelengths. Also, for all three wave heights, the maximum added resistance occurred at a wavelength ratio of 1.8.
