Abstract: | The fluid force coefficients on a transversely oscillating cylinder are calculated by applying two-dimensional large eddy simulation method. Considering the “jump” phenomenon of the amplitude of lift coefficient is harmful to the security of the submarine slender structures, the characteristics of this “jump” are dissertated concretely. By comparing with experiment results, we establish a numerical model for predicting the jump of lift force on an oscillating cylinder, providing consultation for revising the hydrodynamic parameters and checking the fatigue life scale design of submarine slender cylindrical structures. |
