浅水动力学方程的两种格子Boltzmann模型的统一

A uniform Mode of two Lattice Boltzmann Methods for One-dimensional Shallow Water Equations

通过对两种格子Boltzmann模型的研究,建立了一个统一的浅水方程的LB模型,对一维溃坝波进行了模拟计算。通过与文献[1]的结果和精确解作比较,结论显示了此模型的优越性。

Based on the model that refered in reference 1 and reference 3, a uniform lattice Boltzmann model was developed. A one - dimensional dam breaking flow is simulated, and the result are compared with those from other papers and exact solutions. The agreements are satisfactory. It is shown that the model offered in this article has some progress and it is feasible.
