Testes hidrodinâmicos na construção de navios mercantes

Abstract

The construction of vessels requires several steps: since the idealization of the ship until the moment in which the performance of the ship is tested. Among the main stages, the future ship must have its hydrodynamic aspects analyzed. The so - called hydrodynamic tests have the function to de termine the possibi l- ity of building a vessel through testing and projections of aspects such as resistance, ability to maneuver and propulsion. The objective of this study is to characterize the methods used for performing the hydrodynamic tests in a merch ant vessel. In terms of testing, will be addressed the empirical methods and statistical data, the experimental methods in scale models and the numeric methods. In order to exemplify these methods, resistance was chosen as a parameter relevant hydrodynamic behavior of the ship at the preliminary stage, as well as the methodologies for the calculation or estimate of this
