摘要

本文给出了流体力学方程平稳模型的ε -近似,并证明了一个流体力学方程强广义解的存在性定理。利用考虑能量耗散的水动力方程温度模型解的存在唯一性定理证明了这一点。采用Galerkin方法研究了Navier-Stokes方程,从数值和解析两方面证明了不可压缩粘性流动边值问题的正确性。用具有小参数ε的Cauchy-Kovalevsky方程组构造了流体动力学方程的平稳模型和非平稳模型的近似。提出了一种用有限差分法对Navier - Stokes方程进行数值模拟的算法。

The unique solvability of stationary and non-stationary incompressible melt models in the case of their linearization
The article presents ε -approximation of hydrodynamics equations’ stationary model along with the proof of a theorem about existence of a hydrodynamics equations’ strongly generalized solution. It was proved by a theorem on the existence of uniqueness of the hydrodynamics equations’ temperature model’s solution, taking into account energy dissipation. There was implemented the Galerkin method to study the Navier–Stokes equations, which provides the study of the boundary value problems correctness for an incompressible viscous flow both numerically and analytically. Approximations of stationary and non-stationary models of the hydrodynamics equations were constructed by a system of Cauchy–Kovalevsky equations with a small parameter ε . There was developed an algorithm for numerical modelling of the Navier– Stokes equations by the finite difference method.
