In this paper, a commercial CFD code, ANSYS-Fluent has been used to investigate the effect of mesh number generated in the computed domain on the CFD aerodynamic performances of a container ship. A full-scale model of the 1200TEU container ship has been chosen as a reference model in the computation. Five different mesh numbers for the same dimension domain have been used and the CFD aerodynamic performances of the above water surface hull of the ship have been shown. The obtained CFD results show a remarkable effect of mesh number on aerodynamic performances of the ship and the mesh convergence has been found. The study is an evidence to prove that the mesh number has affected the CFD results in general and the accuracy of the CFD aerodynamic performances in particular.

Ship motion responses and added resistance in waves have been predicted by a wide variety of computational tools. However, validation of the computational flow field still remains a challenge. In the previous study, the flow field around the Korea Research Institute for Ships and Ocean Engineering (KRISO) Very Large Crude-oil Carrier 2 tanker model with and without propeller condition and without rudder condition was measured by the authors, as well as the resistance and self-propulsion tests in waves. In this study, the KRISO container ship model appended with a rudder was used for the higher Froude number .26 and smaller block coefficient .65. The experiments were conducted in the Osaka University towing tank using a 3.2-m-long ship model for resistance and self-propulsion tests in waves. Viscous flow simulation was performed by using CFDShip-Iowa. The wave conditions proposed in Computational Fluid Dynamics (CFD) Workshop 2015 were considered, i.e., the wave-ship length ratio λ/L = .65, .85, 1.15, 1.37, 1.95, and calm water. The objective of this study was to validate CFD results by Experimental Fluid Dynamics (EFD) data for ship vertical motions, added resistance, and wake flow field. The detailed flow field for nominal wake and self-propulsion condition will be analyzed for λ/L = .65, 1.15, 1.37, and calm water. Furthermore, bilge vortex movement and boundary layer development on propeller plane, propeller thrust, and wake factor oscillation in waves will be studied.

I would like to begin by juxtaposing two very different pictures of global travel taken from recent articles in the popular media and considering their implications both for contemporary postcolonial theory and for our readings of “third world” fictional texts. In one article from the summer of 1997 (Newton 6-7), the Los Angeles New Times displayed on its cover a slender man in his thirties staring hopelessly out from behind a barred window. The caption read: “No Way Out: Romanian Gavrila Moldovan Risked His Life to Come to America. The INS Promptly Locked Him Up on Terminal Island. Three and a Half Years Later, He’s Still in Jail.” The accompanying story described Moldovan’s desperate flight out of Romania after being declared a “noncitizen” for writing an anti-government news article, which rendered him vulnerable to immediate arrest, and after his parents died in a suspicious car “accident.” Having slipped aboard a container ship bound for the United States together with some fellow countrymen (three of whom died en route), he was discovered and unceremoniously dumped ashore in Panama, only to stow away shortly thereafter on another container ship headed for the Port of Los Angeles. After finally reaching his destination, a “euphoric” Moldovan explained to the US authorities awaiting him at the port: “I come here to be in freedom.... ’” His “welcome” consisted of being arrested and locked up in the INS Processing Center on Terminal Island, in which, though never charged with any crime, he remained for several years before being transferred to Kern County Jail in Bakersfield, where he is currently languishing amongst a population of men awaiting trial for serious crimes (6-7)—one of thousands of refugees and immigrants who have been, and continue to be, incarcerated in prisons that have contracts with the INS, for lack of proper documents, for minor infringements of the law, or because they are denied political asylum despite compelling evidence of their vulnerability to government reprisal at home.
