摘要

摘要:利用不可压缩流体流动的数值分裂方法(SMIF法)，求解了分层环境中混合液体具有初始区间的点链动力学问题和粘性流动问题。SMIF方法具有最小的方案耗散和色散的特点。有限差分格式在空间变量方面具有二阶近似。以给定雷诺数和弗鲁德数的值及初始间隔为参数的特征变异体为例，得到了流函数的场，用于研究斑链动力学。

FLOW PROPERTIES IN THE PROBLEM OF SPOTS CHAIN WITH INTERVALS

A BSTRACT : Authors solves the problem of spots chain dynamics with initial intervals of mixed liquid in stratiﬁed environment, and viscous ﬂow using the numerical splitting method for studying incompressible ﬂuid ﬂows (SMIF method). The SMIF method is characterized by minimal scheme dissipation and dispersion. The ﬁnite difference scheme has the second order of approximation in terms of spatial variables. The ﬁelds of the stream function are obtained, which are used to study the spots chain dynamics using the example of characteristic variant with given parameters of the values of the Reynolds and Froude numbers and initial intervals between spots.
