For information about the equation, its derivation, and its conceptual importance and consequences, see the main article convection–diffusion equation. This article describes how to use a computer to calculate an approximate numerical solution of the equation, in a time-dependent situation. In order to be concrete, this article focuses on ''heat flow'', an important example where the convection–diffusion equation applies. However, the same mathematical analysis works equally well to other situations like particle flow. A general discontinuous finite element formulation is needed.〔“Discontinuous Finite in Fluid Dynamics and Heat transfer” by Ben Q. Li, 2006.〕 The unsteady convection-diffusion problem is considered, at first the known temperature T is expanded into a Taylor series with respect to time taking into account its three components. Next, using the convection diffusion equation and equation obtained from the differentiation of this equation. == Equation == 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「Numerical solution of the convection–diffusion 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.
