A New One-dimensional Smoothed Particle Hydrodynamics Method in Simulating Discontinuous Problem

SONG Jun-hao,ZHANG Chao-ying,LIANG Chao-xiang,LI Wen-gui(College of Computer Science and Information Technology,Guangxi Normal University,Guilin 541004,China)  
For simulating discontinuous physical phenomenon,this paper puts forward a new one-dimensional formula based on restoring particle inconsistency in smoothed particle hydrodynamics(RSPH).Applying Taylor series expansion,neglecting the second and higher derivatives,and associating with these equations,the new approach deduces a new kernel and particle approximation without kernel estimation.In the numerical simulation,the new formulation not only remedies the boundary deficiency problem in the original SPH but also more efficiently repairs the truncated integral in kernel approximation caused by discontinuity and eliminates the errors from particle inconsistency in discontinuous region.
