Analysis for Resistance of Underwater Rowing Cable’s Infinitesimal Element Based on Parameterized Method

摘要:

采用将拖缆直径参数化,可以由 Workbench 一键化建模并由 ICEM 的脚本语言自动生成结构化网格。 采用计算流体力学方法(CFD)计算少量不同攻角时拖缆微元的阻力性能,并由三次样条插值的方法计算拖缆微元在特殊攻角下的阻力性能。

Abstract:

To realize parameterization of towing cable’ s diameter, modelling is carried out by Workbench, and the struc- tured grids are automatically generated by scripting language of ICEM. This paper calculates the resistance performance of towing cable’s infinitesimal at some different attack angles by computational fluid dynamics (CFD) method, and computes the resistance performance of towing cable’s infinitesimal elent at specific attack angles by cubic spline interpolation method.

Key words:parameterization; CFD; cubic spline interpolation; structured grid
