英文摘要 | A particle method is presented for solving the scalar conservation laws. The stability of the method is analyzed and its convergence to the unique entropy solution is proved. The main feature of this method is that particles with same sign of mass are allowed to interpenetrate, but those with different sign of mass cancel each other when they meet in their movement. This feature makes the method highly adaptive. Another main feature of this method is that its convergence to the entropy solution in the L1 norm is proved even if it is not written in conservation form and the L1 convergent rate for the Riemann solutions, a shock wave or a rarefaction wave, is shown to be the order of O(epsilon-2+DELTA-t) or O(epsilon-2), respectively, where epsilon and DELTA-t are the size of the particle mass and the timestep (the total number of particles is O(epsilon-1)). Some numerical experiments are presented to illustrate the performance of this method.; Mathematics, Applied; SCI(E); EI; 0; ARTICLE; 4; 1020-1042; 29 |
