It is named after the British scientist W. R. Dean, who studied such flows in the 1920s (Dean, 1927, 1928). == Definition == The Dean number is typically denoted by ''De'' (or ''Dn''). For a flow in a pipe or tube it is defined as: : $\backslash mathit\; =\; \backslash frac\; \backslash left(\; \backslash frac\; \backslash right)^$ where * $\backslash rho$ is the density of the fluid * $\backslash mu$ is the dynamic viscosity * $V$ is the axial velocity scale * $d$ is the diameter (for non-circular geometry, an equivalent diameter is used; see Reynolds number) * $R$ is the radius of curvature of the path of the channel. The Dean number is therefore the product of the Reynolds number (based on axial flow $V$ through a pipe of diameter $d$) and the square root of the curvature ratio. 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「Dean 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.
