翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Film temperature ： ウィキペディア英語版 Film temperature In heat transfer and fluid dynamics, the film temperature ($T\_f$) is an approximation to the temperature of a fluid inside a convection boundary layer. It is calculated as the arithmetic mean of the temperature at the surface of the solid boundary wall ($T\_w$) and the free-stream temperature ($T\_\backslash infty$):〔Incropera & DeWitt ''Fundamentals of Heat and Mass Transfer'', 4th Ed〕 :$T\_f=\backslash frac$ The film temperature is often used as the temperature at which fluid properties are calculated when using Prandtl number, Nusselt number, Reynolds number or Grashof number to calculate a heat transfer coefficient, because it is a reasonable first approximation to the temperature within the convection boundary layer. Somewhat confusing terminology may be encountered in relation to boilers and heat exchangers, where the same term is used to refer to the limit (hot) temperature of a fluid in contact with a hot surface.〔(Film Temperature )〕〔(Bulk and Film Temperatures )〕 == 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「Film temperature」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.
