低阶非局部Navier-Stokes-Korteweg系统的收敛性:序-参数模型

Convergence of a low order non-local Navier-Stokes-Korteweg system: the order-parameter model

Frederic Charve

摘要:

本文考虑C. Rohde在Bandon,Lin和Rogers的作品之后,称为顺序参数模型,其目的是减少在经典局部Korteweg系统(涉及三阶导数)或非局部系统(也由Rohde在Van der Waals的作品之后介绍,并且涉及卷积算子)的情况下遇到的数值困难。我们证明了这个系统有一个唯一的全球解决方案的初始数据接近平衡,我们精确地研究了这个解决方案的收敛到当地Korteweg模型。

英文摘要:

In the present article we consider a capillary compressible system introduced by C. Rohde after works of Bandon, Lin and Rogers, called the order-parameter model, and whose aim is to reduce the numerical difficulties that one encounters in the case of the classical local Korteweg system (involving derivatives of order three) or the non-local system (also introduced by Rohde after works of Van der Waals, and which involves a convolution operator). We prove that this system has a unique global solution for initial data close to an equilibrium and we precisely study the convergence of this solution towards the local Korteweg model.
