Abstract:
Ship motion is one of the most complicated problems in hydrodynamics. These motions accompany with non linear phenomena and their modeling is very difficult. Analytical solution for governing equations for such problems is not possible and experimental study is very expensive. In this state we need remarkable time for investigating of influences of environmental condition changes. In previous research done by Jahanbakhsh and Panahi,a software created that could solve fluid domain and rigid body equations. But the software needs to be developed in some aspects. Aim of this research is expanding of rigid body motion section of software. The software is capable of getting force or moment and determines six degree motions. It’s not capable of simulating of ship appendages and their influences. Current research goal is modeling of hydrofoil,propeller,rudder,trimtab and interceptor. First for all of appendages adequate information gathered,then modeling algorithm designed and added to software and finally algorithm investigated and modeling results assessed
