... ABSTRACT: The in-line forces on small square cylinder caused by both waves (regular and irregular) and currents based on the extend Morison Equation and model test were analyzed and results are detailed in this paper. The hydrodynamic coefficient Cd and Cm related to KC number and the effect...

... component, whereas equation (8) is the inertia force component. The expressions of the drag coefficient CD and the inertia coefficient CM in the Morison equation have been subjects of many research works, and still need to be more precisely determined. In this study, in order to explicitly calculate...
