Heat Diffusion Equation

The mass transfer equation was introduced into heat transfer model of falling film evaporation. The radial velocity, mass diffusion coefficient and variation of film thickness were taken into account.

将传质方程引入到垂直管降膜蒸发传热模型中，求解时考虑了径向速度、质量扩散系数和膜厚变化对传热的影响。

Heat equation is the most typical one of parabolical equations, which describes many physical-phenomenas, such as conduction, diffusion. Etc.

如描述热传导、扩散等物理现象的热传导方程就是最典型的抛物型方程。

It is one of the basic problems to study the heat conduction equation (the diffusion equation) using numerical method on unstructured grids.

在非结构化网格中，数值求解标量扩散方程(导热方程)是当今数值计算的基础问题。
