Outline The Methodology/Experimental Design: Due To Lack of Experimental

This document outlines the methodology for developing a numerical tool to investigate hydrodynamic interaction phenomena between freely floating 3D bodies. The methodology involves: 1) Creating a computer code to discretize body surfaces and formulate potential flow equations for multiple bodies. 2) Developing the code to compute added mass, damping, wave exciting forces, and response operators by solving the linearized equations of motion. 3) Validating the code by comparing results to published multiple body problems. 4) Obtaining output for variations in parameters like panel arrangements, body size, number of bodies, gaps, and wave angles.

Outline the Methodology/Experimental Design: Due to lack of experimental


facilities, this research work is basically concerned with the development of a
numerical tool to investigate the hydrodynamic interaction phenomena. The
methodology will follow the following steps:
a. Develop a computer code that will be able to discretize the wetted surface of
freely floating 3D box-shaped bodies into identical as well non-identical panel
arrangements.
b. Develop mathematical formulations based on three-dimensional source
distribution technique for the solution of the linearised velocity potential
problem, assuming fluid to be inviscid, homogeneous, irrotational and
incompressible. During the development of the formulations necessary
boundary conditions for multi-body problem will be included.
a. Develop a computer code based upon the mathematical formulations that will
be able to compute the followings:
i) hydrodynamic reaction force and moments, expressed as added mass
and damping coefficients due to the fluid-body interaction.
ii) first order wave exciting forces and moments including the diffraction
effects of the wave on the body.
iii) response amplitude and phase operators that can be obtained from the
linearised set of equations of motion, where the first order wave
exciting forces and moments together with the added mass and
damping coefficients will be used.
b. Validate the computer code by comparing present results with published
results for multiple floating body problem.
c. Obtain the output for the variation of different parameters as panel
arrangements on the wetted surface of the bodies, size of the bodies, no. and
arrangement of bodies, gap between the bodies and wave heading angle.
d. Present the output of the computer code as tabular and graphical form to
illustrate the effect of hydrodynamic interaction.
