等熵可壓縮Navier-Stokes方程解的整體適定性與大時(shí)間性態(tài)
發(fā)布時(shí)間：2020-12-15 17:38
在物理中,Navier-Stokes方程組是以Claude-Louis Navier和 George Gabriel S-tokes命名的,是描述流體介質(zhì)運(yùn)動(dòng)的基本方程。將牛頓第二定律應(yīng)用于流體運(yùn)動(dòng),假設(shè)流體的應(yīng)力項(xiàng)是耗散項(xiàng)（速度的梯度）和壓力之和,那么我們就可以得到該方程。它是描述粘性流體的基本方程。關(guān)于Navier-Stokes方程的重要性,一方面源于它在氣象學(xué),海洋流體力學(xué),繞機(jī)翼空氣流體力學(xué)等方面的廣泛應(yīng)用,另一方面,從純數(shù)學(xué)非線性本身意義上也是極為重要的。本文借助Navier-Stokes方程組,研究了三維無(wú)限區(qū)域內(nèi),氣體的穩(wěn)定性與大時(shí)間的漸近性態(tài)。我們集中討論等熵可壓縮Navier-Stokes方程。文章安排如下：第一章介紹了一些物理背景和相關(guān)的研究進(jìn)展,并介紹了論文中的主要問(wèn)題和方法。第二章,我們研究了一個(gè)無(wú)限拉伸的球內(nèi)可壓縮流光滑解的全局存在性。這是一個(gè)很有趣的問(wèn)題,它涉及到可壓縮Navier-Stokes方程在一個(gè)依賴時(shí)間的區(qū)域內(nèi),并在時(shí)間趨向無(wú)窮時(shí)會(huì)出現(xiàn)真空情況下的解的性質(zhì)的研究。氣體的運(yùn)動(dòng)被三維等熵可壓縮Navier-Stokes方程描述。從物理的觀點(diǎn)來(lái)看,由于氣...
