系列船型变换与自动画网格研究

Research on Series Form Transformation and Automatic Drawing Grid

摘要: 在船舶性能的研究中，经常会用到系列船型，以便使研究的对象有连续的变化。本文探讨了得到系列模型的一般原理，并结合Maxsurf软件实现船型变换过程。在系列船型的基础上，进一步讨论在数值计算的网格划分工作。为了充分利用系列船型的相似性，基于Gambit中的jou文件尝试系列船型自动建立计算域与网格的划分。该方法原理简单，实用性强，当系列船型数量较多时，该方法可以节省时间。

Abstract: Serial ship models are often used in the research of ship performance, so that the object has a continuous change in the study. This article discusses the general principles of how to get the series of ship model, and realizes the change process combining with the Maxsurf software. On the basis of the serial ship models, how to mesh them in the CFD research is discussed. In order to make full use of the similarity of hull form of serial ship models, we try to study grid autogeneration of the serial ship models through the JOU file of the Gambit. This method has simple principles with great practical value, and it can save time when there are a lot of ship models.
