In this blog post, I will try to give a description of the governing equation of the laplacianFoam in OpenFOAM that solves a simple Laplace equation, e.g. for thermal diffusion in a solid. Governing Equation The heat conduction equation is given by the following equation: ∂T∂t=1ρ...
这些方程的解析求解一般有：分离变量法；积分变换法；格林函数法；分离变量法可以求解简单的齐次方程或者可化为齐次方程的偏微分方程（齐次边界），解析结果为无穷级数解。积分变换一般是傅里叶或者拉氏变换，一般要根据方程的特点和边界条件来选择，最终的结果是一个不可积的积分。格林函数法适用于特殊区域...

If the heat source is equal to zero, this reduces to the Fourier equation. If the temperature in the solid is invariant with respect to time, this becomes the Poisson equation. Furthermore, if the temperature is time-invariant and the heat source is zero, this becomes the Laplace equation....
The basic equation governing heat transfer in the HRSG is: Q=UALMTD where: Qis the amount of heat transferred; Uis the overallheat transfer coefficient; Ais the heat transfer surface area; and LMTD is thelog mean temperature difference. ...
