Numerical Simulation of Wave–Current Force Characteristics of Horizontal Floating Cylinder in Heave Motion

This paper presents the characteristics of heave motion responses and hydrodynamic forces a horizontal floating circular cylinder during wave–current interaction. A two-dimensional numerical model based on CFD (Computational Fluid Dynamics) method for modeling wave flow is validated verified. The were calculated analyzed under conditions different k values (stiffness spring), amplitudes, submerged depths, rates. results show that, with increase in value, vibration amplitude first increases then decreases. peak achieved, frequency consistent frequency, resonant takes place. When rate are fixed, maximum decreases as period increases. half-submerged, effect current significant; less than amplitude. quarter submerged, larger that half-submerged at each k. greater amplitude, reaches minimum moderate
