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.
