It is named after Jacques Hadamard and Witold Rybczynski: :$W\_b\; =\; \backslash frac\; \backslash frac$ \frac where * $R$ is the radius of the bubble. * $g$ the gravitational acceleration. * $\backslash rho\_b$ the density of the bubble. * $\backslash rho\_o$ the density of the ambient fluid. * $\backslash mu\_b$ the viscosity of the bubble. * $\backslash mu\_o$ the viscosity of the ambient fluid. The Hadamard–Rybczynski equation can be derived from the Navier–Stokes equations by considering only the buoyancy force and drag force acting on the moving bubble. The surface tension force and inertia force of the bubble are neglected.〔 〕 ==References== 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「Hadamard–Rybczynski equation」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.
