| Abstract: | The development background and theoretical basis of the Smoothed Particle Hydrodynamics(SPH)are introduced herein,and then its applications on the simulations in aspects of the sea ice,the river ice and the free-surface flows etc.are analyzed.As a meshless pure Lagrange method,its major advantages and disadvantages are listed on the basis of the comparison with the other methods and the countermeasures to improve its defects are summarized based on the recent domestic and overseas studies as well. |
