Interpolation and extrapolation of hydrodynamic coefficients

Applied Ocean Research, 1983
Abstract The solution to the problem of calculating the hydrodynamic forces on multiple floating bodies is summarised. The complex coefficients which characterise the forces at each frequency of oscillation are expensive to compute; interpolation of intermediate values and extrapolation to high frequencies appear difficult since the coefficients seem

Hydrodynamic coefficients of a vertical circular cylinder

Canadian Journal of Civil Engineering, 1990
The added mass and the damping coefficient of a large surface-piercing circular cylinder extending to the seabed and undergoing horizontal oscillations are described. A closed-form solution to the corresponding linear radiation problem is obtained by the use of eigenfunction expansions.

Hydrodynamic Coefficients of a Moored Semisubmersible in Waves

Journal of Offshore Mechanics and Arctic Engineering, 1992
The hydrodynamic coefficients of a semisubmersible undergoing slow-drift oscillation were determined through a model test. The semisubmersible model was moored in head seas, fore and aft, with linear springs which were pretensioned and never became slack during any test run.

Hydrodynamic Coefficients and Depth Parameter

Journal of Waterway, Port, Coastal, and Ocean Engineering, 1985
The in-line forces measured on a small section of a fixed vertical cylilnder in waves are analyzed to determine the effects of the hydrodynamic coefficients on the water depth parameter or the orbital shape parameter, Ω. The coefficients, C\dM, C\dD as well as an rms force coefficient, C\dF derived from these forces are found to be insensitive to the ...

Bridge Piers—Hydrodynamic Force Coefficients

Journal of the Hydraulics Division, 1968
The forces experienced by models of three different types of bridge piers have been measured for angles of inclination between the stream flow and the pier axis in the range 0○ to 50○, and the results are presented in the form of drag coefficients and lift coefficients.

Hydrodynamic friction coefficients for cellodextrins in water

Journal of Polymer Science Part A: General Papers, 1965
AbstractThe diffusion coefficients for the cellobiose through cellohexaose members of the cellodextrin series were determined in water. The molecular friction coefficients calculated on the basis of the Einstein diffusion equation can be represented by, ζN = N ζa + 2ζe, where ζa is the monomeric friction coefficient of an anhydroglucose unit, ζe is a ...

Hydrodynamic coefficients for a vertical tube in an array

Applied Ocean Research, 1981
Abstract In a wave tank test with vertical tube array arranged transverse to the wave direction, forces on two 1 ft instrumented sections as well as on the tubes are measured. The effect of the spacing of the tubes upon the forces on the tubes are investigated. The mass and drag coefficients are determined from the forces on the instrumented sections

Frequency Dependence of Hydrodynamic Coefficients in Roll

SNAME 29th American Towing Tank Conference, 2010
A series of tow tank tests were performed to determine whether the added mass moment of inertia in roll and damping roll coefficient for a planing hull are frequency dependent. The model was forced in roll while running at planing speeds. The model was free to heave and pitch, but restrained in sway and yaw. The roll motion, pitch motion, speed and the
