Dissertation/Thesis Abstract

Numerical simulation of free surface viscous flows around single and multiple hulls
by Mucientes, David F., M.S., California State University, Long Beach, 2010, 87; 1493043
Abstract (Summary)

In this work, a comprehensive methodology was developed to analyze the hydrodynamic behavior of single and multiple hulls using STARCCM+ software. Firstly, a Wigley parabolic hull was generated using CAD software, based on the equations that define this type of hull. Using this shape, a fixed trim single hull, with and without wind over calm water were analyzed in order to validate the software against experiments. Subsequently, a Wigley hull with twodegrees of freedom (DOF) over calm water was used to determine the main characteristics of it. A damping factor for the pitch and heave was later added to this two DOF case in order to determine the role that this parameter play in the simulation of the hull motion. After that, the methodology was expanded to study a three DOF single hull case over calm water as well as with incoming waves Finally, a simplified version of a seatrain concept using three Wigley hulls in a row with a determined spacing, over calm water, was computed to analyze its drag and wave patterns.
