عنوان انگلیسی Propeller connection to diesel engine in two shaft line designs of a catamaran passenger ship
چکیده انگلیسی مقاله
The engine braking power moves the ship and it is converted into effective power by taking into account the propulsion power losses and the propeller efficiency. The braking power diagram must be in a suitable position relative to the continuous power diagram and the maximum power of the engine to ensure safe engine operation. In this paper, the propulsion system of a catamaran passenger vessel is investigated and the matching condition of the propulsion components in two shaft line designs and their impact on the performance of the engine and vessel are analyzed in detail. The hull is subjected to CFD analysis and the resistance is calculated. Then, using the hydrodynamic coefficients of the propeller, the matching calculations of the propeller to the engine have been done.  To match the propulsion system, the gearbox with 2.963:1 was coupled with the shaft line. The shaft line design is satisfactory in ship maneuvering and diesel engine performance. The ship's resistance was calculated by STAR-CCM+ software, used in matching calculations and the results have been validated by sea trials. The error between sea trial and matching calculations is a maximum of 7%.
