| Abstract: | A two-dimensional sloshing phenomenon in liquid tank is analyzed by using Smoothed Particle Hydrodynamics method（SPH）.In order to analyze the influence of different liquid tank,＂I＂ and ＂T＂ shape baffles are used in this study.For the sake of analyzing the effect of sloshing in different liquid tank,different size of baffles is studied in this work.From the result of numerical analysis,the height of baffle between 60 percent and 80 percent of water depth is suitable for reducing the impulse pressure.For the performance of reducing sloshing motion,rectangular tank with ＂T＂ baffle is better than that of ＂I＂ baffle.Based on the result of computation,the numerical method proposed by this work can be used to analyze the motion and pressure of liquid tank.Furthermore,the present numerical method can be used to assist the designing of structure in the liquid tank. |
