Another necessary assumption is that all the fields of interest like pressure, flow velocity, density, and temperature are differentiable, weakly at least. The equations are derived from the basic principles of conservation of mass, momentum, and energy. For that matter, sometimes it is necessary to consider a finite arbitrary volume, called a control volume, over which these principles can be applied. This finite volume is denoted by $\backslash Omega$ and its bounding surface $\backslash partial\; \backslash Omega$. The control volume can remain fixed in space or can move with the fluid. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Derivation of the Navier–Stokes equations」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
