Moving particle semi-implicit (MPS)flow model is improved by introduction of the spline function used in the smoothed particle hydrodynamics (SPH)model as the kernel function and some modifications for the diffusion and gradient submodels.
通过引入SPH(smoothed particle hydrodynamics)方法中的样条函数作为核子函数,并进一步修正扩散模型及梯度模型的计算公式,对已有MPS(moving particle semi-implicit)水流数学模型进行了改进。
Without grids, the interaction effect among neighboring particles can be simulated by means of the kernel function, based on which the governing equation is discretized by establishing the smoothing model, the gradient model and the second-derivative mod.
在无网格条件下,粒子间的相互作用通过核子函数来表示,并通过建立物理量光滑模型、梯度模型和二阶导数模型来离散控制方程。
Moreover,we discuss the relation between the quotients of a generalized frame A and the nucleus functors on A.
进而讨论了一个广义frame A的商与A上核函子之间的关系。
