可压缩流体流动欧拉方程解的极限性态

Limiting behavior of solutions for Euler equations of compressible fluid flow

Manas Ranjan Sahoo, Abhrojyoti Sen

摘要:

研究了一维可压缩流体流动的欧拉方程解在类压同类项项为零时的极限行为。这个系统可以看作是宇宙大尺度结构形成的一维模型的一个近似。当初始数据为Riemann型时,前一方程的解在分布意义下收敛于后一方程的解,并与粘性消失极限一致。本文还研究了宇宙大尺度结构形成的一维模型的另一种近似。

英文摘要:

We study the limiting behavior of the solutions of Euler equations of one-dimensional compressible fluid flow as the pressure like term vanishes. This system can be thought of as an approximation for the one dimensional model for large scale structure formation of universe. We show that the solutions of former equation converges to the solution of later in the sense of distribution and agrees with the vanishing viscosity limit when the initial data is of Riemann type. A different approximation for the one dimensional model for large scale structure formation of universe is also studied.
