in dynamic analysis of floating structures, the designer needs to know the wave forces due to incident and scattered waves on the structure. in this work, the flow field around the body is solved based on the potential theory with considering the free surface and sea bed effects. using this theory, the wave forces exerted on two typical sea buoys with spherical and disc-type bodies are determin...

nowadays, due to the increasing power of diesel engines, especially heavy duty diesel engines, and increasing gas pressure inside the combustion chamber, the forces acting on the engine bearings have dramatically raised. on the other hand, becaus eof the competition in the market, it is necessary to increase the engine bearing life and reduce its failure as much as possible. the engine bearings...

measuring sensitivity of hydraulic structures is considered as an approach for evaluation of water projects performance, due to lower distribution efficiency in irrigation and drainage project schemes. sensitivity analysis approach for irrigation structures is one of flow analysis methods which are developed in recent years in order to measure the behavior of flow in hydraulic structures in an ...

most codes such as api and bsi recommend morison’s equation to estimate hydrodynamic forces on offshore structures. significant differences exist among these codes due to using different methods of analysis and estimation of force coefficients. in this paper, data from full scale tests have been used to evaluate random waves and uniform current actions on the smooth piles. four time and frequen...
