The function of coefficients of added mass of water [PDF]

open access: yesE3S Web of Conferences, 2023
The hydrodynamic effect of the water mass of the reservoir on the pressure face of the dam can be determined from the function of the coefficient of the added mass of water obtained in the Westergard solution.

Cavitation Effects on the Structural Resonance of Hydraulic Turbines: Failure Analysis in a Real Francis Turbine Runner

open access: yesEnergies, 2018
When discussing potential resonances in hydraulic turbine runners, cavitation effects are usually neglected. Nevertheless, recent studies have experimentally proved, that large cavitation volumes in the proximity of flexible simple structures, such as ...

Ships Added Mass Effect on a Flexible Mooring Dolphin in Berthing Manoeuvre

open access: yesJournal of Marine Science and Engineering, 2021
This paper deals with the hydrodynamic effect of the ship on a flexible dolphin during a mooring manoeuvre. The hydrodynamic effect refers to the change in momentum of the surrounding fluid, which is defined by the concept of added mass.

Investigation into the Potential Use of Damping Plates in a Spar-Type Floating Offshore Wind Turbine

open access: yesJournal of Marine Science and Engineering
Spar is one of the promising floating platforms to support offshore wind turbines. Wind heeling moment is large in the case of floating offshore wind turbines and, therefore, it is important to reduce the pitch motion of the floating platform. To address

Airship Motion Modeling Based on a Dynamic Aerodynamic Model

open access: yesGuidance, Navigation and Control
A dynamic modeling method for relating the motion parameters and aerodynamics of an airship is proposed to solve the parameter determination, fusing, and frequency-matching problems that exist in the present airship aerodynamic models. Firstly, the added-
