翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Weber number ： ウィキペディア英語版 Weber number The Weber number (We) is a dimensionless number in fluid mechanics that is often useful in analysing fluid flows where there is an interface between two different fluids, especially for multiphase flows with strongly curved surfaces. It is named after Moritz Weber (1871–1951). It can be thought of as a measure of the relative importance of the fluid's inertia compared to its surface tension. The quantity is useful in analyzing thin film flows and the formation of droplets and bubbles. ==Mathematical expression== The Weber number may be written as: :$\backslash mathrm\; =\; \backslash frac$   where * $\backslash rho$ is the density of the fluid (kg/m3). * ''v'' is its velocity (m/s). * ''l'' is its characteristic length, typically the droplet diameter (m). * $\backslash sigma$ is the surface tension (N/m). The modified Weber number, :$\backslash mathrm^$ *=\frac   equals the ratio of the kinetic energy on impact to the surface energy, :$\backslash mathrm^$ *=\frac}, where :$E\_\backslash mathrm=\backslash frac$   and :$E\_\backslash mathrm=\backslash pi\; l^2\; \backslash sigma$. 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「Weber number」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.
