摘要
本文引用映象平面ξ～Ψ,建立了轴对称流道A型杂交气动命题的变分原理族。本文旨在为轴对称流道气动设计提供一些更广泛、灵活的途径,并为有限元法建立完密的理论基础。
In this article a family of variational principles for solving the hybrid aerodynamic problem of type A of axisymmetric channel flow is developed on an image plane ξ-ψ for providing more broad and versatile ways for channel design and a theoretical basis for finite element applications.
