Finite Point Method for Inverse Heat Conduction Problem with Moving Boundary
对带有移动边界的非齐次热传导方程反问题进行研究,利用一种基于动态节点布置策略的无网格有限点法求解该问题.当带有噪声数据时,求解源项为不适定问题,结合磨光正则化方法,对方程的源项以及精确解进行同时反演.通过数值算例验证,文中所用方法对于求解此类带有移动边界的热传导方程反问题是稳定有效的.
The inverse problem of non-homogeneous heat conduction equation with moving boundaries is studied,and a meshless finite point method based on dynamic node arrangement strategy is used to solve the problem.When there is noisy data,solving the source term is an ill-posed problem.In this paper,combining the smoothing regulariza-tion method,the source term and the exact solution of the equation are simultaneously inverted.Numerical examples show that the method used in the article is stable and effective for solving inverse problems of heat conduction equa-tions with moving boundaries.
