摘要

我们解决的问题，评估目标函数的形状导数的辐射传递工程涉及半透明介质。在回顾了灵敏度估计的标准蒙特卡罗方法及其局限性的基础上，针对几何灵敏度的具体情况，提出了一种新的方法。然后在一个方形腔中测试该方法，该腔中填充了多重散射和吸收(非发射)半透明介质，并由发射圆柱体照射。提出了一种新的几何灵敏度算法，该算法具有充分的通用性，便于在复杂几何中实现。

MONTE-CARLO AND DOMAIN-DEFORMATION SENSITIVITIES

We address the question of evaluating shape derivatives of objective functions for radiative-transfer engineering involving semi-transparent media. After recalling the standard Monte-Carlo approach to sensitivity estimation and its current limitations, a new method is presented for the specific case of geometrical sensitivities. This method is then tested in a square cavity filled by a multiple-scattering and absorbing (non-emitting) semi-transparent medium, irradiated by an emissive cylinder. A new geometrical sensitivity algorithm is presented with full genericity in order to allow its future implementation in complex geometries.
