| 摘 要： | 针对填埋场释放气体运移问题的求解方法进行了研究,提出了空间上运用无网格伽辽金法离散而时间上采用增维精细积分法离散的新解法,导出了相关的数值计算公式。结果表明,本解法的数值解与理论解吻合较好。本方法的计算过程稳定性和精度受时间步长大小影响比有限差分法小得多。前后数据处理相当方便。

| Abstract: | The solutions of landfill gas transport in MSW landfills were investigated.A new solution in which spatial and time domains were discretized using the element-free Galerkin method and increment-dimensional precise integration method respectively was put forward,and its corresponding formulae were deduced.Results show that its solution is consistent with theoretical one.The effect of time step size on its stability of computational process and accuracy is smaller than that in FDM.Its before-after data dispos... |
