Added massCFDDampingHeave platesOversetRadiationFluid鈥搒tructure interaction processes of heave damping plates in forced vertical motion are investigated using a CFD numerical model. First, a single isolated disk is considered with two submergence depths, including a case where the disk is very close...
Numerical investigation into combined global and local hydroelastic response in a large container ship based on two-way coupled CFD and FEA Using the present strongly coupled method, the added mass with regards to the elastic deformation of the ship is reflected in the results of a decrease ......
The main aim of this paper is the numerical investigation of the effect of domain size and mesh density on modeling the three-dimensional (3-D) the radiation problem using RANS CFD software. The solution for the radiation forces and moments, namely the added mass and damping coefficients, is...
Viscous effects also have a small influence on added mass and possibly radiation damping and this is a secondary consideration. In spite of the widespread use of cylindrical bodies offshore there is little information on drag coefficients, at least in the open literature. While CFD is ...
However, a second body in diffraction theory, when chosen properly with respect to size and shape, can contribute to the correct calculation of the added mass and damping of vessels on sloped seabeds as this varies with the local ... B Buchner 被引量: 19发表: 2006年 Using CFD to Determi...

The CFD (Computational Fluent Dynamics) method was used to calculate the added mass and the viscous damping of the Spar platform considering the semi-closed moon pool in this paper. The three-dimensional models of the platform with water inside the semi-closed moon pool were established by the...

This paper investigates the formation mechanism of the propulsive force of a flapping airfoil, which performs harmonic angular oscillations in a continuous medium flow, in the light of the recently proved general theorem on the added mass of bodies in a viscous incompressible fluid. The flow is de...
Moreover, the models show quantitative agreement with the CFD as well as EFD samples in long waves and qualitative agreement with their trend in the short wave regime. However, both the resonance frequency and the corresponding magnitude are not very well captured. Lastly, the semi-empirical ...
