Base on Newton's second law, particle movement equation in water can be express as: p p d p m. Among these methods, the 3- D method is used generally for structures comprising large structural members. Particles suffer from the viscous force, the added mass force and the pressure gradient force in the cone section of straight cone nozzle. The existing methods for the hydrodynamic forces on offshore structures are mainly based on one of the following: Morison's equation, two-dimensional (2-D) and three- dimensional (3-D) source-sink distribution techniques. Straight cone nozzle structure as shown in Fig. The calculation procedure derived in this paper provides a very efficient means of calculating wave forces and moments during the time-domain simulations of a floating platform experiencing large amplitude motion in intact, progressive flooding and damaged conditions. The acceleration equation of particle in the nozzle.

These parts underwent several alterations, and since this. The key components of managing the reliability of this measurement are the nozzles and the test section (No. At the end of the paper, expressions of total heave, sway and surge forces and total roll, pitch and yaw moments acting on the platform are given as a sum of these forces acting on each member of the platform. The confuser nozzles are specifically manufactured for each artery size, so that disturbances could vanish entirely before the test section. In the procedure of calculating wave forces presented, definitions of the wave reference systems for propagating wave, the structure reference system for the platform and the member reference system for the tubular members of the structure are first established, and then the calculation of wave forces is given in terms of its components, which are pressure, acceleration and velocity forces, including current forces. Calculation procedure of wave force components is presented in great detail on the basis of wave particle kinematic properties obtained from the linear Airy wave theory. This method of calculating wave forces is based on the linear Airy wave theory. By means of the proposed method one can calculate the wave loading on cylindrical members of fixed or floating offshore structures orientated randomly in waves. This paper presents the derivation of a general method for calculating wave forces on the cylindrical members of offshore structures. A GENERAL METHOD FOR CALCULATING HYDRODYNAMIC FORCES
