关于薄绝缘层的最优形状

On the optimal shape of a thin insulating layer

Paolo Acampora, Emanuele Cristoforoni, Carlo Nitsch, Cristina Trombetti

AI总结:

该研究针对有界开集的薄绝缘层隔热问题,采用Γ-收敛一阶渐近展开方法,分析绝缘层厚度趋于零时的极限情形,为薄绝缘层最优形状研究提供渐近分析思路。

摘要:

我们关注有界开集$Ω$的隔热问题,该集合被一层厚度局部由$\varepsilon h$描述的材料包围,其中$h$是定义在边界$\partialΩ$上的非负函数。我们利用$Γ$-收敛的一阶渐近展开,研究$\varepsilon$趋于零时的极限问题。

英文摘要:

We are interested in the thermal insulation of a bounded open set $Ω$ surrounded by a set whose thickness is locally described by $\varepsilon h$, where $h$ is a non-negative function defined on the boundary $\partialΩ$. We study the problem in the limit for $\varepsilon$ going to zero using a first-order asymptotic development by $Γ$-convergence.
