A preliminary design tool for resistance and powering prediction of catamaran vesselsZouridakis, Fragiskos January 2005 (has links)
Thesis (Nav. E. and S.M.)--Massachusetts Institute of Technology, Dept. of Ocean Engineering, 2005. / Includes bibliographical references (p. 86-87). / During the last decade catamaran ships have been very rapidly evolved into a dominant mode of sea transportation. Their particular area of proliferation is the short sea shipping where they show considerable superiority over competitive designs in attributes such as power requirements, economy, space availability and seakeeping. The rapid growth of the market has led to the need for an expanded range of catamaran designs in terms of size, speed, and payload diversity (passengers, vehicles, containers). However, even now, there is a scarcity of publicly available preliminary design tools for catamarans. This fact hinders the ship owner and naval architect from being able to quickly assess the relative merits of alternative potential designs without having to resort to expensive expert consultancy solutions. Resistance characteristics and power requirements are principal aspects of the catamaran design spiral as they are strongly coupled with speed and fuel economy, and, consequently, the operating and cost efficiencies of the vessel. This thesis aims towards the development of a tool that predicts the resistance and required power for catamaran vessels in the range of 20m to 80m. Vessels with both round bilge and hard chine hulls are considered. / (cont.) Reasonable accurate prediction may be achieved for all speed regions of intended operation. (Displacement, semi-displacement and planning) The user will be able to select both propellers and waterjets for the propulsion of the vessel. For any given vessel size and operational profile the user will be able to determine the most efficient design by altering a series of inputs related to ship geometry and propulsor characteristics. Besides preliminary powering predictions, the tool has the potential to assist in parametric trade-off studies by exploring sets of hull form - propulsor combinations due to its ability to produce variants within a very short time frame. / by Fragiskos Zouridakis. / Nav.E.and S.M.

Velocity characteristics in the wake of an oscillating cylinderDavis, Joshua Tolford, 1978- January 2001 (has links)
Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Ocean Engineering, 2001. / Includes bibliographical references (leaves 100-102). / This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections. / This thesis describes the results of over 2000 experimental runs conduced at the MIT Ship Model Testing Tank. A rake of constant temperature anemometers is employed to study the spanwise velocity correlation and the vertical velocity profile downstream of a vibrating cylinder. Experiments involve either free vibration implemented through a force feedback system or forced sinusoidal motion. All experiments are conducted at a towing speed within the subcritical flow regime at Re ~ 3 x 104. This thesis explores the connection between these downstream velocity properties and the vortex-induced vibrations of the cylinder. In addition to downstream velocities, experimental data include lift and drag forces and cylinder displacement. Vortices are found to be correlated along the entire length of the test cylinder only within a specific band of motion amplitudes and frequencies. Overall, forced oscillations produce vortices that are more organized and well correlated than those shed from a freely vibrating cylinder. / by Joshua Tolford Davis. / S.M.
