Variational Principle of Pseudo-potential Function for Two-Dimension Rotational Flow
Sun Jie-jing · Journal of Jinan Uniuersity · 2005
Two Linkaqiao constraints have been changed into one through analyzing Hamilton principle in Euler space in detail. On the basis of Euler equations given in this paper, we derived the momentum equations from another viewpoint. Natural boundary conditions were constructed by analyzing boundary terms of variational principle, and further variational principle of pseudo-potential function for calculating two-dimension flow field was derived.
