| 中文摘要 | Without shear effect, Cai et al. [Cai S, Long X, Gan Z. A method to estimate the forces exerted by internal solitons on cylindrical piles. Ocean Eng 2003;30(5):673-89; Cai S, Wang S, Long X. A simple estimation of the force exerted by internal solitons on cylindrical piles. Ocean Eng 2006;33(7):974-80] introduced Morison's empirical formula and modal separation method to estimate the forces and torques exerted by internal solitons on cylindrical piles. However, due to the residual Currents, there always exist shear flows in the ocean. In this paper, the observational data recording a passage of the internal soliton near Dongsha Islands are used to compute the force and torque exerted by the internal soliton in shear flows on a supposed pile for comparison with the nonshear case. It is found that the effects of the shear on the computed wave speed, wave form, environmental parameters of the nonlinear internal wave, the corresponding force and torque on the cylindrical pile are important. When different modal waves are retained in the calculations, both forces and torques exerted by the internal soliton in a shear flow on the pile are larger than those without shear, especially for the estimated torques. The uncertainty of the estimates is also discussed. (C) 2008 Elsevier Ltd. All rights reserved. |
