提出了一种优化方案和矩阵划分策略，并结合边界元法求解传热反设计问题。最优控制问题是将内部加热或冷却通道定位在涂覆的传导域内，以在指定热通量时实现期望的边界温度（反之亦然）。由于内部通道可以用少量变量进行参数化，因此优化问题是低维的。边界元系统的矩阵划分方案和优化搜索过程导致这类问题的快速计算方案。
An optimization scheme and matrix partitioning strategy are developed in conjunction with a boundary element solution procedure for inverse design in heat transfer. The optimal control problem is to locate interior heating or cooling passages inside a coated conducting domain to achieve a desired boundary temperature when the heat flux is specified (or vice versa). As the interior passages can be parameterized with a few variables, the optimization problem is of low dimension. The matrix partitioning scheme for the boundary element system and optimization search procedure lead to a fast computational scheme for this class of problems.
