摘要

摘要本文主要研究了一个非线性粘性流体运动模型的弱可解性，该模型具有沿速度场决定的流体粒子轨迹的记忆。在证明所述模型的可解性时，我们使用了研究流体力学问题的拓扑近似方法--正则拉格朗日流理论。文中证明了非线性粘性流体至少存在一个弱解。

Investigation of Weak Solvability of One Model Nonlinear Viscosity Fluid

Abstract

This paper is devoted to investigating the weak solvability of one model nonlinear viscosity fluid motion with memory along the trajectories of fluid particles determined by the velocity field. We used the topological approximation method for studying hydrodynamic problems, the theory of regular Lagrangian flow, when proving the solvability of the described model. The existence of at least one weak solution of the nonlinear viscosity fluid is proved in the paper.
