冰区航行船舶碎冰阻力预报数值模拟方法
A numerical simulation method for resistance prediction of ship in pack ice
摘要
Abstract
As more and more countries have recognized the huge potential value of the arctic, performance research and design work of ship in pack ice are drawing more and more attention of people. In order to study the ship resist⁃ance in the crushed ice area, this paper uses the penalty function algorithm and fluid structure interaction algorithm of ls⁃dyna software to carry out numerical simulation for the sailing process in crushed ice, and calculates the force between ship and ice at four speed points under 60%, 80% and 90% of crushed icedensities. On the basis of non⁃refrigerated ice model test in ship model towing tank, the results of numerical simulation is analyzed. The results of numerical simulation are in good accordance with the test results on qualitative level at low speeds. Numerical simu⁃lation method has important reference value for the research work of ship resistance in ice region.关键词
