| Abstract: | The basic principles of SPH method for smooth ion fluid dynamics,nuclear function and discrete forms of governing equations as well as boundary treating methods are introduced here.Then the numerical flume model is established accordingly,and the water interface deformation,screen breaking,bubble formation and collapse after opening the gate,as well as the swell generation process are simulated successfully.The results show that the fluid splash and fusion phenomena could be captured by using SPH method,and the method is suitable for the transient simulation with the great water movement and deformation. |
| Keywords: | smooth ion fluid dynamics water movement no grid numerical simulation |
