The effect of spacing transverse to the wave direction on the Morison force coefficients in two cylinder groups
- Univ. of Melbourne, Victoria (Australia). Dept. of Civil and Environmental Engineering
This paper provides some results from an experimental study currently being carried out in the Michell laboratory at the University of Melbourne. The principal purpose of the study is to investigate the Morison in-line hydrodynamic force characteristics of slender surface-piercing multi-cylinder structures. The test program has been tailored to provide more detailed observations within the close-spaced region (Separation/Diameter ratio, s/D < 2) of the group interference effect in such multi-cylinder structures over the Keulegan Carpenter range 0 < KC < 20 which encompasses the inertia force dominant Morison regime (KC < 5), as well as the so-called troublesome region (5 < KC < 15) where both drag and inertia force components are significant. Results currently in hand for the side-by-side two-cylinder group configuration are presented which clearly depict the characteristics of this interference effect.
