Title: Large Eddy Simulation of Three-Dimensional Wave-Current Interaction with Vertical Square Cylinders in Tandem Arrangement
Abstract: To study wave-current interaction with square cylinders in tandem arrangement, a three-dimensional numerical model is established. The large eddy simulation (LES) method is used to model the effect of small-scale turbulence. The mean value, fluctuating drag coefficients, and vortex shedding properties caused by the non-linear wave-current interaction with square cylinders of centre-to-centre cylinder spacing ratios between 2 to 5 are numerically simulated. Results show the mean value, fluctuating drag coefficient, and the Strouhal number of the two cylinders are sensitive to the various spacing ratios. When the spacing ratio reaches its critical value of 4, the relevant parameters of the two cylinders alter rapidly, especially for that of the downstream cylinder.
