摘要:

提出了磁流体动力学(MHD)平衡的伴随公式,用于灵敏度分析和基于优化的平衡计算。我们推导了固定边界条件下三维平衡方程的伴随算子,并分析了其轴对称约化。约化后的算子与扰动Grad-Shafranov算子一致,从而明确了三维伴随构造与轴对称伴随问题之间的联系。所得框架为关联轴对称和全三维理想MHD平衡中的伴随结构提供了基础。

英文摘要:

Adjoint formulations of magnetohydrodynamic (MHD) equilibrium are presented for sensitivity analysis and optimization-based equilibrium calculations. We derive the adjoint of the three-dimensional equilibrium equations under fixed-boundary conditions and analyse its axisymmetric reduction. The reduced operator coincides with the perturbed Grad-Shafranov operator, thereby making explicit the connection between the threedimensional adjoint construction and the axisymmetric adjoint problem. The resulting framework provides a basis for relating adjoint structures in both axisymmetric and fully three-dimensional ideal MHD equilibrium.
