Research on the Horizontal Force of Internal Solitary Waves to the Vertical Cylinders

Based on the fluid simulation software: Fluent, a numerical flume was established in which a vertical cylinders was placed. On the basis of internal solitary wave theories: KdV and mKdV, four internal solitary waves with different amplitudes were made by the use of speed entry method; simultaneously, the horizontal force of each cylinder was calculated. And then a cylinders with the same size was put into the 2d internal wave flume in the laboratory; internal solitary waves were made using gravity collapse method and the horizontal forces of the cylinders with different depths were measured when the internal waves passed. The experimental results which were gained from the comparison of the numerical simulation results with those of the experiment certified the feasibility of the simulation. Furthermore, distribution of the horizontal force along the vertical direction was also analyzed in this paper.
