Abstract
The dynamics characteristic of aerial towed cable has been investigated with many models. Because of the coupling between the components of the towed cable system, the dynamics of the towed cable is complex and nonlinear. Though the aerodynamic performances of cable is studied for a long time, the results are quiet different with researchers. The ideal method to obtain the aerodynamic forces is to simulate the flow structure around the towed cable.The purposes of this paper are to simulate the flow field of the towed cable with the different inclined angles by using Large Eddy Simulation (LES) with sub-grid scale model of Smagorinsky-Lily and to study the variation of the aerodynamic forces and its influences on flow structure. The results show that the LES can predict the flow structure of the cable reasonably.
